Some constellations are more prominent in the night sky of North Carolina in winter, while other constellations are more prominent in the night sky in summer. Which best explains why this occurs?

• because of Earth's rotation on its axis

• because of stars revolving around Earth

• because of Earth revolving around the sun

• because of the change in barycenter of Earth

What is most likely to occur when the sun, moon, and Earth are aligned in a relatively straight line?

How does the energy produced by the sun travel to Earth?

• by the magnetic fields between the sun and Earth

• by the convection of heat through particles in space

• by the radiation of electromagnetic waves through space

• by the process of conduction of heat between the sun and Earth

Which best describes how energy from the sun helps to maintain life on Earth?

• It heats Earth's atmosphere and surface, which helps stabilize temperatures on Earth and creates environments more favorable for life to exist

• It forms the ocean's water and the oxygen in the atmosphere that organisms need for life functions

• It prevents the destruction of the magnetic field around Earth that protects all life forms

• It is absorbed by Earth's mantle, which drives plate tectonics to form new land masses for organisms to live

This is a diagram of a soil triangle. Farmers can use this chart to identify the type of soil found on their land and determine the likelihood of erosion and other important factors. What type of soil does a farmer have if the coil contains 40% sand, 40% silt, and 20% clay?

• clay

• loam

• silty loam

• sandy loam

What would be most effective in minimizing the potential damage caused by an earthquake?

• installing sirens in areas prone to earthquakes

• building structures that withstand ground vibrations

• increasing the amount of concrete during road building

• requiring the recycling of metal and wood products

Bedrock that is closer to oceanic ridges is younger in age than bedrock that is farther away. What can best be concluded from this information?

• The shape of Earth's lithosphere is continually changing.

• The moment of continental plates is caused by volcanic eruptions

• The oceans are becoming deeper and warmer as more rocks are produced.

• The rocks on the ocean floor are producing tectonic plates that are converging
