Earth's Spheres

What is the definition of Spheres in Earth science?

• Spheres are layers of the Earth that include the crust, mantle, and core.

• Spheres are subsystems that categorize all matter on Earth, including the atmosphere, hydrosphere, biosphere, and geosphere.

• Spheres refer to the different types of rocks found on Earth.

• Spheres are the various climates that exist on Earth.

How do human activities impact the Earth's spheres?

• Human activities can lead to pollution, climate change, and habitat destruction, affecting all Earth's spheres.

• Human activities have no significant impact on the Earth's spheres.

• Human activities only affect the atmosphere and not the other spheres.

• Human activities improve the health of the Earth's spheres.

What does the Latin prefix 'Bio-' mean?

• Living Things

• Dead Things

• Artificial Objects

• Non-Living Entities

How does the Hydrosphere interact with the Geosphere?

• The Hydrosphere shapes the Geosphere through processes like erosion and sediment deposition.

• The Hydrosphere has no effect on the Geosphere.

• The Hydrosphere only affects the atmosphere, not the Geosphere.

• The Hydrosphere and Geosphere are completely independent of each other.

How does water vapor in the atmosphere relate to the Hydrosphere?

• Water vapor is a form of precipitation that falls to the ground.

• Water vapor is part of the Hydrosphere as it represents water in its gaseous state within the atmosphere.

• Water vapor is not related to the Hydrosphere at all.

• Water vapor is a solid form of water found in the atmosphere.
