Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor, usually due to heat from the sun.

Front

What effect does evaporation have on nearby land areas?

Back

Evaporation can lead to increased precipitation in nearby land areas.

Front

What are the common characteristics of waves?

Back

Waves can have the same frequency and wavelength, which means they oscillate at the same rate and cover the same distance in a given time.

Front

What happens to molecules when their kinetic energy increases?

Back

When kinetic energy increases, molecules move faster.

Front

What is density?

Back

Density is the mass of an object divided by its volume, often expressed in grams per cubic centimeter (g/cm³).

Front

How do you compare the densities of two substances?

Back

You can compare densities by determining if one substance is greater than, less than, or equal to the other.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, which is related to the kinetic energy of its molecules.

Front

How does thermal energy move?

Back

Thermal energy moves from objects with higher temperatures to objects with lower temperatures.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the molecules in a substance also increases.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.
