Front

What is the main reason for the changing seasons on Earth?

Back

The tilt of Earth's axis as it orbits the Sun.

Front

What is a tide?

Back

The rise and fall of sea levels caused by the gravitational forces of the Moon and the Sun.

Front

What are spring tides?

Back

Tides that occur when the Sun, Moon, and Earth are aligned, resulting in the highest high tides and the lowest low tides.

Front

What are neap tides?

Back

Tides that occur when the Sun and Moon are at right angles relative to Earth, resulting in the lowest high tides and the highest low tides.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

How does the distance between two objects affect gravitational pull?

Back

As the distance increases, the gravitational pull decreases.
