Exploring Earth's Spheres and Currents

Front

What is the Geosphere?

Back

The Geosphere is the solid part of the Earth, including landforms such as mountains, valleys, and the Earth's crust.

What is the Hydrosphere?

Back

The Hydrosphere encompasses all the water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the Atmosphere?

Back

The Atmosphere is the layer of gases surrounding the Earth, essential for weather, climate, and supporting life.

Front

What is the Cryosphere?

Back

The Cryosphere includes all frozen water on Earth, such as glaciers, ice caps, and sea ice.

Front

What are convection currents?

Back

Convection currents are movements in fluids (like air) caused by uneven heating, where warm air rises and cool air sinks.

Front

What is the Troposphere?

Back

The Troposphere is the lowest layer of the atmosphere, where weather occurs and where we live.

Front

What is the Stratosphere?

Back

The Stratosphere is the layer above the Troposphere, containing the ozone layer that protects Earth from harmful UV radiation.

Front

What is the Mesosphere?

Back

The Mesosphere is the layer of the atmosphere above the Stratosphere, where temperatures decrease with altitude.

Front

What is the Thermosphere?

Back

The Thermosphere is the uppermost layer of the atmosphere, characterized by high temperatures and the presence of ionized gases.

Front

How do plants interact with the Atmosphere and Biosphere?

Back

Plants use sunlight to convert carbon dioxide from the atmosphere and water from the biosphere into oxygen and glucose.
