Front

What is heat transfer?

Back

The movement of thermal energy from a warmer object to a cooler one.

Front

What happens to heat when an ice cube is held in a warm hand?

Back

Heat moves from the warmer hand to the cooler ice cube, causing the ice to melt.

Front

Why does the Moon not have an atmosphere like Earth?

Back

The Moon's gravitational pull is too weak to hold an atmosphere.

Front

What is a common characteristic of all moons in the solar system?

Back

They are naturally formed bodies that orbit planets.

Front

What would happen if Earth was no longer in the Sun’s orbit?

Back

Earth would continue moving in a straight line in space.

Front

What occurs when a hot object is placed in a cooler environment?

Back

The hot object cools down as heat moves from it to the cooler environment until both reach the same temperature.

Front

What is gravitational pull?

Back

The force by which a planet or other celestial body attracts objects toward its center.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of an object around its own axis, while revolution is the movement of an object around another object.

Front

What is thermal equilibrium?

Back

A state in which two objects in contact no longer transfer heat, as they have reached the same temperature.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets, moons, and other celestial bodies in orbit around larger bodies like stars.
