Jeremy decides to make a model of the Earth. He makes his model by drawing the Earth on a sheet of paper. When he finishes his model, Jeremy notices that the shapes and sizes of the continents are not correct. He also notices that the Earth's surface is cut off at the edges of the drawing. Jeremy decides that he wants his model to be more accurate. How can Jeremy improve his model so that it is more accurate? A. Use a ruler to draw the continents with straight lines. B. Use a thicker piece of paper. C. Draw the Earth on a sphere. D. Draw the Earth smaller on the paper.

Answers

Answer: C. Draw the Earth on a sphere.

Explanation:

Jeremy should draw the Earth like a small sphere that can be drawn completely on the paper and edges will not be left incomplete. The shape and size of the continent can be traced using a map or a stencil. The exact dimension to be drawn is not important but the boundaries should be taken care of and must be accurate.

Write a summary of the pathways rocks can take to become sedimentary, igneous, and metamorphic rocks.

Answers

Answer:

When a certain type of rock, specifically, an igneous rock, is deeper into the ground, and it is under the influence of high temperatures and pressures, it will start to change its molecular structure over time. In addition to the high temperature and pressure, chemical influences are also very important, so the the rock will gradually turn into a metamorphic rock.

 Depending on the type of influences, and their intensity as well, one type of rock can evolve into multiple different types of metamorphic rocks.

Explanation:

The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.

Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their  differences as they currently exist.

B-are made out of organic material that stores the sun energy

C-form where there are frequent earthquakes and volcanic activity

D- are produced high in the mountains where temperatures are low

Answers

Answer:

maybe C i'm so sorry if this is wrong

Explanation:

Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.

What are fossil fuels?

An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.

Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.
