Describe three characteristics of the crust

Answers

Answer 1

Three characteristics of the crust include;

Compose of solid rock Less dense than oceanic crust Undergoes tectonic activity

How can the crust be described ?

The Earth's crust consists mainly of firm rock and minerals, including basalt and granite. This layer is the thinnest amongst all three comprising layers of our planet, having a thickness ranging from 5-70 kilometers.

There are two types primarily that make up this crust - oceanic and continental. Oceanic crust has an average density approximating 3.0 g/cm³ in contrast to continental crust being less dense with an average density of about 2.7 g/cm³. The movement of the earth's plates (tectonic activity) constantly shifts the crust, leading it to face geological events like earthquakes, volcanoes, etc.

Explanation:

. Please calculate the confidence interval based on the conditions below

Answers

With 90% confidence, we can say that the true population mean is between 11.448 miles and 12.552 miles.

How to explain the confidence interval

Confidence interval = sample mean ± margin of error

The margin of error is determined by the sample size, the standard deviation, and the level of confidence.

Standard error = population standard deviation / √sample size

Standard error = 3 / √80 ≈ 0.3354

Confidence interval = sample mean ± margin of error

Confidence interval = 12 ± 0.552

Confidence interval = (11.448, 12.552)

Therefore, with 90% confidence, we can say that the true population mean is between 11.448 miles and 12.552 miles.

Look at the description of the Sherburne. How was the distance to/ from the shore of the sea changing in the area as the Sherburne was being deposited?
Why are there no fossil ferns or primitive pine trees

Answer from your tutor:

Answers

The Sherburne formation is starting to become sandier the closer you get to the top because the shore is starting to transition to sandstone.

How did the distance to/from the shore change as Sherburne was deposited?

The Sherburne formation refers to sequence of sedimentary rocks that was deposited in the Late Cretaceous period in what is now Montana and Wyoming which is thought to have been deposited in a shallow marine environment with the shoreline fluctuating over time.

As the Sherburne was being deposited, the distance to/from the shore of the sea was changing in the area. At the bottom of the formation, the sediment is composed of finer-grained rocks such as shale and mudstone which indicate a more offshore environment.

But as you move up the formation, the sediment becomes coarser with the sandstone and conglomerate becoming more prevalent which suggests that the shoreline was moving closer and the area was becoming shallower.

The loss of natural habitat for animals and insects is cost because it is like a danger to the ecosystem .

What is the effect of habitat loss?

Habitat loss, can be described as the removal of plants as well as the trees that helps in the process of the stabilizatio of the soil, which bring about the increase in the erosion, as well as fading away the nutrient levels in terrestrial ecosystems.

It should be noted that this can bring about the decrease agricultural productivity. and can bring about the biodiversity as well as negatively impact the ecosystem

E. , understand this material). Normally, protons repel each other because their charges are similar, and by analogy consider trying bring together the N of a magnet with the N of another magnet. To overcome that electromagnetic repulsion one needs to smash the protons at a very high speed, and then nuclear fusion can occur. That high speed is not achieved in daily life, thankfully, but in the cores of stars where the temperature is high. Temperature is a proxy for the speed of particles, and as an example consider if it is cold in the room the particles are moving slowly. The temperature is high in the cores of stars because there is the sizable mass of all the overlaying layers exerting a pressure on the core, and causing the temperature to rise, and hence the speed of the protons. By analogy, consider when diving from the top of the pool to the bottom of the pool, and where one begins to feel the pressure exerted by all the overlaying layers of water
