A seismograph records four earthquakes of magnitude 3.7, 3.2, 6.5 and 4.3 and then seismicity decreases. Which earthquake(s) represent (a) foreshock(s)

Answers

Answer 1

Foreshocks are simply known as an earthquakes that often comes before a larger earthquakes in the same location. The earthquake 3.7 and 3.2 represent a foreshock.

Foreshocks as an earthquake cannot be said to be a foreshock until after a larger earthquake in the same area occurs.

Earthquakes that fall between the ranges of 3.0 to 3.9 on the scale are said to be small or minor earthquakes.

In this type of earthquakes, one can feel the earthquake, and objects inside shaking around, but it rarely damage.

C. The temperature of the universe has warmed over time.

Answers

The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

D)

Answers

According to the information, we can state that global temperatures tend to increase as carbon emissions increase, as shown in option A.

We can arrive at this answer because:

According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.

These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

Erosion occurs on the outside curve of meanders. Why is this?

Answers

Answer:

max velocity of the stream goes towards the outside of the bend causing an erosion of the bank. (more specifically the outer bank)

Explanation:

Meanders shift their position by eroding downstream and sideways. The stream's highest velocity changes to the outside of the curve, eroding the outer bank and resulting in the sideways flow.

What occurs when a meander makes an outside bend?

The river bank outside of the bend, where water flow has the maximum energy due to less friction, is eroded and undercut by the force of the stream. River cliffs will result from this. Material is deposited inside the bend where the water flow is slower and there is more friction. This will create a slope for sliding off.

A meandering stream moves laterally due to deposition on the inside and erosion of silt on the outside of the meander (which is caused by friction work) (helicoidal flow, deceleration, channel lag, point bar sequence, fining upwards).

Fertilizer adds missing chemicals back into the soil to make the soil more nutrient rich. These chemicals are needed for plants to survive and grow, and many of them are commonly found in the natural environment. How, then, can fertilizer also be a pollutant?

Answers

Excessive use of fertilizers leads to eutrophication. Fertilizers contain substances including nitrates and phosphorus that are flooded into lakes and oceans through rains and sewage. These substances boost the excessive growth of algae in the water bodies, thereby decreasing the level of oxygen for aquatic life.

the rain washes down the chemical fertilizer and discharge then into the river and many water bodies causing water pollution . when they are used the young seed that are sowed falls on them and that acts as a poison in the seeds . the use of chemical fertilizer can led to the spoiling of the quality of the soil

Pumice floats on water because it has an incredibly low density due to the air bubbles inside of it.

The less dense air offsets the more dense rock, causing it to float.

hope it helps

Answer:

There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration

Explanation:

The water cycle depicts the continual flow of water on Earth and in the atmosphere. It's a complex system with many separate processes. Liquid water evaporates into water vapour, condenses into clouds, and precipitates as rain and snow on the ground.

Evaporation, condensation, and precipitation are the three fundamental processes that make up the water cycle. Evaporation is the transformation of a liquid's surface to a gas.

Liquid water (from the ocean, lakes, or rivers) evaporates and turns into water vapour in the water cycle. Water vapour is a significant greenhouse gas as well. Evaporation, condensation, and precipitation are commonly taught as a simple circular cycle.

Evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage are all processes that may be examined. When the physical condition of water changes from a liquid to a gaseous state, evaporation happens.

The water cycle is the course that all water takes as it passes through different phases across the Earth. Oceans, rivers, lakes, and even subterranean contain liquid water. The water cycle is the course taken by all water as it travels around our world.
