Review the statements below and identify those that are correct. A. We see different constellations at different times of the year, as Earth travels in its orbit around the Sun B. The rotation of Earth on its axis makes some of the constellations appear to rise in the eastern part of the sky and set in the western part of the sky C. Constellations close to the North Star, such as the Big and Little Dippers and Cassiopeia, do not rise or set. They travel in a circle around the North Star every 24 hours D. The "fixed stars" refer to the location of the constellations on a vast sphere surrounding Earth E. Constellations appear to rise in the east and set in the west because the sphere of stars rotates around Earth every 24 hours

A, B, and C

The Moon goes through a full cycle of phases about once a month E. The stars move in circles around the North Star F. It is colder near the poles than near the equator

A, C, and E

The atmosphere protects against harmful radiation D. Raw materials and nutrients are naturally recycled E. The gravitational field is strong enough to hold an atmosphere F. The temperature range on Earth is suitable for many forms of life G. The atmosphere is composed of appropriate mixture of gases, including greenhouse gases

A,B,C,D,E,F and G

Which of the following are true about the relationship between Earth and the Moon? A. The Moon orbits Earth in an elliptical orbit B.

The sidereal month, or period of the Moon's orbit with respect to the stars is 27 1/3 days E. The Moon orbits Earth in a counterclockwise motion viewed from above Earth's North Pole

All of them

Which of the following best describes how the relative motion of the Sun, Earth, and Moon produce a lunar eclipse? A. A total lunar eclipse occurs when the full Moon's orbit carries it into the umbra of the Sun B. A lunar eclipse occurs when the Moon moves into Earth's shadow C. A lunar eclipse occurs when the Moon moves into a direct line between the Earth and Sun D. A lunar eclipse occurs when Earth moves into the Moon's shadow

B. A lunar eclipse occurs when the Moon moves into Earth's shadow

On October 7, 1959, the Soviet spacecraft Luna-3 took the first fuzzy image of the far side of the Moon. It was an exciting image since only one side of the Moon is visible from Earth. Which pair of statements explains why only one side of the Moon is visible from Earth? A. The rotation of the Moon on its axis takes 27 days, 7 hours, and 43 minutes B. The revolution of the Moon around Earth takes 27 days, 7 hours, and 43 minutes C. The Moon and Earth revolve around each other D. The same side of the Moon and the same side of Earth always face each other

C and D

Mars and Venus both have water in their atmosphere, so Earth is not the only planet in our solar system with water. However, Earth is unique because of the amount of liquid water on its surface. Which of the following factors best explains why Earth supports liquid water on its surface?

Earth's distance from the Sun keeps it in the habitable zone, where liquid water can exist
