Answers

Answer 1
The correct answers are:
2.They were motivated by their desire for freedom.
4.They were warned ahead of time that the British were coming.

Explanation:

The colonists were not well-trained, and they did not have plenty of supplies and equipment. They were mostly farmers and tradespeople, and their militias were not professional armies.
The colonists were highly motivated by their desire for freedom and their opposition to British rule.
General Washington did not command the colonial forces at the Battles of Lexington and Concord. He did not become commander-in-chief of the Continental Army until after these battles.
The colonists were indeed warned ahead of time that the British were coming. Paul Revere and other riders spread the news that the British were marching from Boston to Concord to seize colonial arms and ammunition. This gave the colonists time to prepare and to muster their militia forces.

what is the specific gravity of gem quality diamonds

Answers

The specific gravity of gem quality diamonds is 3.52. Specific gravity is the ratio of the density of a substance to the density of a reference substance.

It is commonly used to determine the purity of gemstones. Diamonds have a very high specific gravity due to their high density and hardness. Diamonds are the hardest naturally occurring substance on earth and they have an extremely high specific gravity.

The specific gravity of diamonds is an indication of how much heavier they are than the same volume of water. For example, a one carat diamond would weigh 3.52 times the weight of the same volume of water. This high specific gravity is why diamonds are so valuable. They have a very high density and are very hard. They are also difficult to cut and polish, which makes them more valuable.

with respect to a warm front where does precipitation occur

Answers

Precipitation generally occurs ahead of a warm front, as the warm air rises over the colder air ahead of it and cools, causing the moisture in the air to condense and form clouds.

Precipitation generally occurs ahead of a warm front as air rises and cools. This is because the warmer air, which is higher in the atmosphere, rises over the colder air ahead of it. As it rises, the air cools, leading to the condensation of moisture in the air and the formation of clouds.

This condensation process eventually results in the formation of rain, snow, or other forms of precipitation, depending on the temperature of the air and other conditions. Knowing the processes behind precipitation can help you better understand weather patterns and plan accordingly.

adding water, a so-called volatile, to a rock tends to lower the melting temperature of its minerals, and thus may allow it to melt if it is sufficiently warm. group of answer choices true false

Answers

The statement is true.

Adding water to a rock, which is a volatile substance, can lower the melting temperature of its minerals. This is because water molecules can break the bonds between the mineral grains and thus make it easier for them to slide past each other. This, in turn, reduces the amount of heat required to melt the rock.

The amount of water required to lower the melting temperature of a rock depends on various factors such as the composition of the rock, the pressure and temperature conditions, and the amount of water available. However, in general, the presence of water can significantly affect the melting behavior of rocks and minerals.

True. Adding water, a volatile, to a rock lowers the melting temperature of its minerals by providing pathways of heat transfer, making it easier for the minerals to melt if the temperature is high enough.

This process is known as hydrothermal alteration, and it is often seen in areas with volcanic activity. This is because the water vapor released during volcanic activity can cause minerals to melt, leading to the formation of magma.

Adding water, or other volatile compounds, to a rock can lower the melting temperature of its minerals, and thus can allow the rock to melt if the temperature is high enough. This is a common process in the Earth's mantle where water is brought down into the mantle via subduction zones and can lower the melting temperature of the mantle rocks, leading to the formation of magma that eventually rises to the surface to form volcanic eruptions.

Why are there high mountain systems in the south of Europe?

Answers

The high mountain systems in the south of Europe, such as the Alps, Pyrenees, and Apennines, are the result of tectonic activity and plate movements that occurred millions of years ago.

During the Mesozoic Era, which spanned from about 252 to 66 million years ago, the African plate began to move northward, eventually colliding with the Eurasian plate. This collision caused the crust to buckle and fold, resulting in the formation of the Alpine mountain range, which stretches from France to Slovenia.

Similarly, the Pyrenees mountain range, which runs along the border between France and Spain, was formed by the collision of the Iberian plate and the Eurasian plate around 50 million years ago.

The Apennine Mountains in Italy are also the result of tectonic activity, specifically the convergence of the African and Eurasian plates.

Answers

The character of rock influences weathering through minerals that are soluble and can be dissolved and reprecipitated and so are resistant to weathering. Hence, option B is correct.

When they come into contact with water, air gases, and living organisms, rocks, soils, substances, wood, and man-made objects all deteriorate as a result of weathering.

The two different types of weathering processes are physical weathering and chemical weathering. The biological degradation of rocks and soils brought on by heat, water, ice, or other substances is known as physical weathering. Chemical weathering is the result of interactions between water, gases from the atmosphere, and chemicals produced by living beings with rocks and soils. Water is principally responsible for both chemical and physical weathering, with considerable contributions from air oxygen, carbon dioxide, and living things. Chemical weathering brought on by biological activity is also known as biological weathering.

Some types of rock exhibit remarkable degradation resistance. Igneous rocks weather slowly because water has a hard time penetrating them, especially intrusive igneous rocks like granite. Other types of rock, like limestone, are more subject to weathering since they dissolve in weak acids.

if there is a stack of rocks and the bottom layer is sandstone, the middle layer is shale, and the top layer is limestone, what does that represent regarding sea level?

Answers

The stack of rocks and the order of the rock layers represents the history of sea-level changes.

Sandstone, shale, and limestone are sedimentary rocks that were formed from the accumulation of sediment at the bottom of the ocean or a large lake. As sea level changes, the type of sediment that is deposited on the ocean floor changes as well. Sandstone is typically formed in shallow waters, near the shoreline. As sea level rises, the shoreline moves inland, and the deposition of sandstone is replaced by shale. Shale is formed in deeper waters, where there is less sediment and the water is calmer.

When sea level drops again, the deposition of shale is replaced by limestone. Limestone is formed in clear, shallow waters, where there is a lot of sunlight for the growth of coral and other marine life. The layers of rock in the stack can indicate that there have been multiple cycles of sea-level changes over time, with each layer representing a different period of time when the ocean was at a different level.

Answers

Human activities have impacted the rate of soil erosion in various ways. The option that explains this is that humans have increased the rate of soil erosion by removing vegetation through activities such as farming, logging, and construction.

By removing vegetation cover, human activities have left the soil exposed to wind and water erosion. This has led to soil erosion occurring at a faster rate than would happen naturally.Human activities that have caused soil erosion include deforestation, construction, farming on steep slopes, logging, and mining.

Human activities have led to soil erosion happening faster than natural processes can replace the eroded soil. This has had a negative impact on soil productivity, water quality, and aquatic ecosystems.Grassed waterways have, however, been one of the measures adopted to control soil erosion.

Grassed waterways are designed channels that are constructed on slopes to allow for the natural flow of water. These channels are covered with vegetation, and their design helps reduce the speed and volume of water runoff, thus reducing the impact of water erosion on soil.

Why are there volcanic eruptions in Europe?

Answers


As Africa has pushed northwards against Europe the floor of the Mediterranean has sunk into the mantle along a crack in the earths crust along subduction zones causing new magma to rise to the surface.
Volcanic eruptions in Europe are caused by the movement of tectonic plates. Europe is located on the boundary of the Eurasian, African, and Arabian plates, which are all actively moving. When these plates move against each other, it can cause the formation of magma chambers beneath the Earth's surface. As pressure builds up within these chambers, it can cause volcanic eruptions. Additionally, Europe is home to a number of active and dormant volcanoes, such as Mount Etna in Italy, which can also experience eruptions due to the movement of tectonic plates or other factors such as changes in the geothermal activity of the region.

*NO LINKS ALLOWED! ANY ANSWER WITH LINKS RESULTS INTO A REPORT.* Brainliest will be given to the first person to answer effectively.

Answers

Answer:

Explanation:

Glaciation played a significant role in the formation of the hills and valleys seen in southern Ontario's landscape. During the last ice age, which lasted from about 110,000 to 12,000 years ago, much of North America was covered by a massive ice sheet called the Laurentide Ice Sheet. This ice sheet was responsible for carving out many of the valleys and hills in southern Ontario.

As the ice sheet advanced and retreated, it ground the underlying rock and soil, creating deep grooves and channels. As the ice sheet melted, the water carried away the loose material, leaving behind valleys and depressions. The retreat of the ice sheet also left behind moraines, which are ridges of glacial debris that were deposited along the ice sheet's edge.

In addition to the physical erosion caused by the ice sheet, glaciation also had an impact on the region's hydrology. The melting of the ice sheet created vast amounts of meltwater, which carved new river channels and contributed to the formation of the many lakes and wetlands in the region.

Overall, the combination of physical erosion and changes in hydrology caused by glaciation played a significant role in shaping the hills and valleys of southern Ontario's landscape. These features serve as a reminder of the powerful and transformative effects of glaciation on the region's geology and ecology

explain how the thermohaline circulation (thc) works and how temperature and salinity changes; near the ocean surface and in the ocean depths. how does evaporation change ocean salinity?

Answers

Thermohaline circulation (THC) is the global ocean circulation pattern driven by temperature and salinity differences. Near the ocean surface, the temperature of the ocean is determined by air-sea interactions. The salinity near the ocean surface is determined by the amount of evaporation from the ocean and the amount of precipitation that falls into the ocean.

As the ocean water gets deeper, the temperature and salinity become more constant. In the depths of the ocean, salinity is determined by the amount of dissolved salts that have been slowly sinking from the upper layers of the ocean. Evaporation from the ocean surface removes fresh water from the surface and leaves the saltier water behind, making the ocean surface water more saline. Precipitation, however, adds fresh water to the ocean and thus decreases the salinity of the ocean.

Answers

The majority of ozone is found in the c) stratosphere, which is located between the troposphere and the mesosphere.

This is because the stratosphere is where the ozone layer is located, a region where ozone concentrations are high enough to effectively absorb ultraviolet radiation from the sun.

The troposphere, which is the lowest layer of the atmosphere and where weather occurs, contains much lower concentrations of ozone. In fact, ground-level ozone can be harmful to human health and is a major component of air pollution. Ozone is not found in the mesosphere or paleosphere in significant quantities.
