Unit1: Earthrise the Big Picture (SchoolNet)

The gravitational force of the Sun is powerful enough to hold Earth in orbit even though Earth is an average of 150 million kilometers away. Which statement BEST describes why objects with much less mass than Earth are NOT pulled off the surface of Earth toward the Sun?

• Objects on Earth are orbiting the Sun too quickly.

• Objects on Earth have too little mass on which to pull.

• Objects on Earth are held by the gravity of the Moon.

• Objects on Earth are most influenced by Earth’s gravity.

Fish can live in lakes that are frozen because liquid water remains below the ice at the surface. Which of these describes a property of water that allows some liquid water to remain in frozen lakes?

• Water can dissolve many different substances.

• Water is less dense as a solid than as a liquid.

• Water has a Mohs hardness of about 2 when it is frozen.

All of the planets in the solar system formed at about the same time from a large cloud of gas and dust. How is Earth different from other planets in the solar system?

• Earth has no natural satellites.

• Earth’s atmosphere is composed of gases.

• Water is found in all three phases on Earth.

• Volcanoes release liquid rock onto Earth’s surface.
