Oceans and Atmosphere

Front

What is the Stratosphere?

Back

The Stratosphere is the second layer of Earth's atmosphere, located above the Troposphere and below the Mesosphere. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What is the primary reason planes fly in the Stratosphere?

Back

Planes fly in the Stratosphere because all weather events occur in the Troposphere, making the air in the Stratosphere thinner and more stable for flight.

Front

What is another name for the Thermohaline circulation?

Back

The Great Ocean Conveyor Belt.

Front

What is the Thermohaline current?

Back

The Thermohaline current is a deep ocean current that moves water around the globe, driven by differences in temperature and salinity.

Front

What gas makes up most of the Earth's atmosphere?

Back

Nitrogen, which constitutes about 78% of the atmosphere.

Front

What is the Ozone Layer?

Back

The Ozone Layer is a region of Earth's Stratosphere that contains a high concentration of ozone (O3) and protects living organisms by absorbing harmful ultraviolet radiation from the sun.

Front

What is the Troposphere?

Back

The Troposphere is the lowest layer of Earth's atmosphere, where weather occurs and where most of the atmosphere's mass is found.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of Earth's atmosphere, located above the Stratosphere and below the Thermosphere, where temperatures decrease with altitude.

Front

What is the Thermosphere?

Back

The Thermosphere is the layer of Earth's atmosphere above the Mesosphere, characterized by high temperatures and the presence of ionized gases.

Front

What is the Halocline?

Back

The Halocline is a layer in the ocean where there is a rapid change in salinity with depth.
