Unit 2 Review

What characteristic of Earth allows water to exist as a liquid?

• the distance between the planet and the Sun

• the rotation of the planet on its axis

• the orbit of the planet around the Sun

• the tilt of the planet on its axis

One theory states that by the year 14000, the axis of Earth will point towards the star Vega. This is due to the very slow wobble of the axis of Earth.

Which change is most likely to occur because of the movement of the axis?

• Seasons will become more severe

• Winter and summer months will reverse

• More daylight will increase temperatures

• Glacial coverage will expand near the poles

Lunar phases occur when the Moon appears to change shape as seen from Earth. What causes different phases of the Moon?

• the alignment of the Sun, Moon, and Earth in a straight line

• the tilt of the earth

• the shadow of Earth falls on the Moon

• the amount of the sunlit side of the Moon that faces Earth

A lunar eclipse occurs when the Moon passes through Earth’s shadow. A total lunar eclipse can only occur during a

• full moon

• new moon

• 1st quarter moon

• last quarter moon

Which of the following is the most rare to observe from Earth?

• total solar eclipse

• total lunar eclipse

• partial solar eclipse

• partial lunar eclipse

Garden plants on Earth require four resources to stay alive: soil, air, water, and sunlight. How many of these resources are necessary for life to exist on another planet or the Moon?

• 4

• 3

• 2

• 1

What kind of eclipse is occurring where the arrows are pointing?

• partial solar

• partial lunar

• total solar

• total lunar

On Earth, tides are constantly changing from high to low and back again. A neap tide is a high tide that is lower than normal. This drawing shows the configuration of the Sun, the Moon, and Earth when a neap tide is formed.

Why is the high tide unusually low when the Sun, the Moon, and Earth are in this configuration?

• because gravitational forces of the Sun and the Moon are working against each other

• because the Sun and the Moon are in this configuration for a short period of time

• because the axis of Earth is tilted toward the Moon but away from the Sun

• because Earth is closer to the Moon than it is to the Sun

What are the reasons for the season?

• Earth's tilt & rotation
• Earth's tilt & revolution
• Earth's rotation & rovolution
• Earth's tilt & resolution
