Space Flashcard Review - Seasons/Gravity/Tides

Front

What is the force that holds all of the planets in orbit around the sun?

Back

Gravity

Front

What are the two measurements that are both expressed in Newtons?

Back

Force and weight

Front

In which position would the northern hemisphere be during winter?

Back

Position W

Front

What season occurs in the Northern Hemisphere when the Earth is tilted away from the sun?

Back

Winter

Front

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

Back

Because Jupiter has more mass, and therefore more gravity.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which depends on its mass.

Front

What causes the change of seasons on Earth?

Back

The tilt of the Earth's axis and its orbit around the sun.

Front

What is the effect of gravity on tides?

Back

The gravitational pull of the moon and the sun causes tides in Earth's oceans.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

How does the distance from the sun affect the seasons?

Back

The tilt of the Earth's axis, not the distance from the sun, primarily affects the seasons.
