Gravity and The Habitable Zone 7.9B and 7.9C

Front

What is gravity?

Back

Gravity is an attractive force between any two objects with mass, acting on both the objects and the Earth.

Front

True or False: Objects with greater mass have greater gravity.

Back

True

Front

Why would a person weigh more on Jupiter than on Earth?

Back

Because Jupiter has more mass, and therefore more gravity.

Front

What keeps planets in their orbit?

Back

Gravity.

Front

What is one complete orbit called?

Back

Revolution.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the greater its gravitational pull.

Front

What is the habitable zone?

Back

The habitable zone is the region around a star where conditions may be right for liquid water to exist on a planet's surface.

Front

What factors determine the habitable zone of a star?

Back

The habitable zone is determined by the star's luminosity and temperature.

Front

How does gravity affect the habitable zone?

Back

Gravity helps to retain an atmosphere, which is crucial for maintaining liquid water in the habitable zone.

Front

What happens to gravity as distance from a mass increases?

Back

Gravity decreases as the distance from the mass increases.
