Earth Spheres

What is the significance of the geosphere in Earth's systems?

• It provides the foundation for landforms and habitats.

• It regulates the climate and weather patterns.

• It is responsible for the Earth's magnetic field.

• It controls the distribution of water on the planet.

What are the three main Earth spheres interacting when a polar bear is floating on an iceberg in the ocean?

• Cryosphere, Biosphere, Hydrosphere

• Atmosphere, Lithosphere, Biosphere

• Hydrosphere, Atmosphere, Geosphere

• Cryosphere, Lithosphere, Atmosphere

What is the term for all the landforms on Earth?

• Geosphere

• Biosphere

• Hydrosphere

• Atmosphere

What role does the cryosphere play in Earth's climate?

• It reflects sunlight and helps regulate temperature.

• It absorbs heat and increases global temperatures.

• It contributes to ocean acidification.

• It has no significant impact on climate.

What is the relationship between the cryosphere and hydrosphere?

• The cryosphere is a part of the hydrosphere, consisting of frozen water.

• The cryosphere is completely separate from the hydrosphere.

• The cryosphere is a type of ocean current within the hydrosphere.

• The cryosphere refers to the gaseous state of water in the hydrosphere.

Which of the following is part of the geosphere?

• Mountains

• Rivers

• Atmosphere

• Oceans

Name one example of a landform found in the geosphere.

• Mountains

• Oceans

• Deserts

• Forests

How does the atmosphere affect the biosphere?

• It provides essential gases for respiration and photosynthesis.

• It regulates the temperature of the Earth's surface.

• It blocks harmful solar radiation.

• It creates weather patterns that influence ecosystems.

What is an example of an interaction between the hydrosphere and geosphere?

• Rivers eroding rocks and soil.

• Clouds forming from ocean evaporation.

• Plants absorbing sunlight for photosynthesis.

• Wind blowing sand dunes across a desert.

What is the difference between the hydrosphere and the atmosphere?

• The hydrosphere includes all water bodies, while the atmosphere includes all air and gases.

• The hydrosphere is the layer of soil, while the atmosphere is the layer of rocks.

• The hydrosphere is only the oceans, while the atmosphere is only the clouds.

• The hydrosphere includes all living organisms, while the atmosphere includes only the sun's rays.
