Unit 4 Science Review Moreno

The picture shows a model that Ms. Garcia uses in her science class. Ms. Garcia places a globe on a table. She shines a flashlight on the globe and spins it on its axis. Which statement best describes what Ms. Garcia's model demonstrates?

• A. The length of the year is caused by Earth's orbit around the Sun.

• B. Moon's phases are caused by the Moon's orbit around Earth.

• C. The number of seasons is caused by the tilt of Earth's axis.

• D. Day and night are caused by Earth's rotation on its axis.

Which statement best describes a benefit of a telescope in space?

• It can collect samples from remote places on Earth that can be analyzed.

• It can travel to other stars and planets in the solar system to collect data.

• It can get clearer pictures without light pollution or atmospheric interference.

• It can perform computations much faster than a telescope on the ground.

Why does it look like the Sun is moving across the sky during the day?

• A. Earth is revolving around the Sun each day, causing day and night.

• B. The Sun is revolving around Earth, moving across the sky during the day.

• C. Earth is rotating on its axis, making it look like the Sun is moving across the sky.

• D. The Sun is rotating on its axis, causing it to appear in different parts of the sky.
