What is the atmosphere?

Front

What are the five layers of the atmosphere?

Back

1. Troposphere 2. Mesosphere 3. Stratosphere 4. Thermosphere 5. Exosphere

Front

____________ happens in the troposphere.

Back

weather

Front

The _________ in the stratosphere protects us from the Sun’s UV radiation.

Back

Ozone layer

Front

Which layer does the ISS (international space station) orbit in the atmosphere?

Back

thermosphere.

Front

Where does the exosphere extend?

Back

into space.

Front

Why is heat transfer important in the troposphere?

Back

Heat transfer is important because the movement of heat in the troposphere affects our temperature, wind, and precipitation.

Front

What is conduction?

Back

Conduction is the direct transfer of heat from one substance to another substance through touch.

Front

How do radiation, conduction, and convection work together to heat the troposphere?

Back

The sun moves energy and heats the ground through radiation. Conduction warms the ground air and heats the lower atmosphere. Air molecules touch each other and transfer heat. The warm air rises and cool gases sink through convection.

Front

Why do we have seasons?

Back

The tilt of Earth’s axis and its revolution around the Sun causes seasons.
