Science 4 Spheres Of Earth Flash Cards

1. What is the hydrosphere?

The layer of gases surrounding the Earth

The relatively thin layer of water that covers 3/4 of the Earth's Surface. It contains glaciers, oceans, rivers, ponds, lakes, water vapour and so on...

The outer layer of the Earth's atmosphere

The solid portion of the Earth's surface

The hydrosphere refers to the water component of the Earth. It includes all the water sources on Earth, such as oceans, rivers, lakes, etc.

Explanation

The hydrosphere refers to the water component of the Earth. It includes all the water sources on Earth, such as oceans, rivers, lakes, etc.

2. What is the atmosphere?

The deepest layer of the Earth's core.

The body of water surrounding the Earth.

This relatively thin layer is the outermost sphere of the Earth. It contains weather and has a great influence over climate. It is also composed of various layers.

The layer directly beneath the Earth's crust.

The atmosphere refers to the layer of gases surrounding the Earth. It plays a crucial role in sustaining life on the planet by regulating temperatures and providing the air we breathe.

3. What is the geosphere composed of?

Hydrosphere

Atmosphere

This sphere is the densest of them all. It's composed of the crust, the mantle and a metal core. It contains Earth and rock.

Hyalosphere

The geosphere is characterized by its density and composition of Earth's crust, mantle, and metal core, containing primarily Earth and rock. The terms 'Hyalosphere,' 'Atmosphere,' and 'Hydrosphere' refer to other components of the Earth that are not part of the geosphere.

Explanation

The geosphere is characterized by its density and composition of Earth's crust, mantle, and metal core, containing primarily Earth and rock. The terms 'Hyalosphere,' 'Atmosphere,' and 'Hydrosphere' refer to other components of the Earth that are not part of the geosphere.

4. What sphere contains all living organisms?

Atmosphere

Geosphere

This sphere contains all living organisms. It's Alive!

Hydrosphere

The biosphere refers to the sphere on Earth that contains all living organisms. The geosphere refers to the solid parts of Earth, the hydrosphere refers to all the water on Earth, and the atmosphere refers to the layer of gases surrounding the planet.

Explanation

The biosphere refers to the sphere on Earth that contains all living organisms. The geosphere refers to the solid parts of Earth, the hydrosphere refers to all the water on Earth, and the atmosphere refers to the layer of gases surrounding the planet.

5. What are constructive forces?

Forces that destroy landmasses. An example are Erosion and Weathering.

Forces that impact the atmosphere. An example are Cloud Formation and Rainfall.

Forces that create landmasses. An example are Earthquakes and Volcanoes.

Forces that cause droughts. An example are Hurricanes and Tornadoes.

Constructive forces are geological processes that build up the Earth's surface by creating new landforms, while destructive forces break down landforms. Examples of constructive forces include tectonic plate movements leading to earthquakes and volcanic eruptions, which result in the formation of new landmasses.

Explanation

Constructive forces are geological processes that build up the Earth's surface by creating new landforms, while destructive forces break down landforms. Examples of constructive forces include tectonic plate movements leading to earthquakes and volcanic eruptions, which result in the formation of new landmasses.

6. What are destructive forces?

Forces that strengthen landmasses.

Forces that have no impact on landforms.

Forces that create landmasses.

Forces that wear down landmasses. An example are rain, ice, wind and hail. They wear down through the process of weathering and erosion.

Destructive forces are natural processes that break down and wear away landmasses over time, contrasting with constructive forces that build up landforms. Examples like rain, ice, wind, and hail contribute to the gradual erosion and weathering of the Earth's surface.
