Heated Earth Investigation 4 vocabulary

Front

What is radiation?

Back

Radiation is the transfer of energy in the form of waves, such as heat from the sun or a candle flame, that can travel through space.

Front

Which molecules have more energy, hot or cold?

Back

Hot molecules have more energy than cold molecules.

Front

What is convection?

Back

Convection is the circular movement of fluids (like air or water) caused by uneven heating, where warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What are variables in an experiment?

Back

Front

What is the Hydrosphere?

Back

The Hydrosphere is all the water on Earth, including water in solid (ice), liquid (water), and gas (water vapor) forms.

Front

What is conduction?

Back

Conduction is the transfer of heat energy through direct contact between materials.

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is the role of the sun in the water cycle?

Back

The sun provides energy that causes water to evaporate, turning liquid water into water vapor, which is essential for the water cycle.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with each other and their environment.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding Earth, essential for life and weather.
