Question

1 multiple choice 20 points
weathering, or the breaking down of rock material on earths surface, occurs in the geosphere. which of the statements about earth systems impacts this process?
the biosphere, through the work of plants, could physically and chemically change the rock material.
all of these earth systems impact the rate of weathering in the geosphere.
the atmosphere impacts weathering by producing acid rain that could alter the rock material.
the hydrosphere impacts weathering by producing water dissolving and or physically breaking the rock material.

2 multiple choice 20 points
when thinking about the systemic nature of planet earth, why might resource sustainability and conservation be important considerations?
resources availability in one earth system will not impact other earth systems.
resource sustainability and conservation help to ensure the earth system continues to function properly.
the resources of the earth system are unlimited and do not require conservation.
living things on earth do not depend on resources for survival.

3 multiple choice 20 points
which of the statements most correctly explains how the biosphere works within the earth system?
the biosphere only impacts the atmosphere
the biosphere is influenced by the geosphere and atmosphere
the biosphere is impacted and influenced by the hydrosphere, geosphere, and atmosphere
the biosphere is impacted only by the hydrosphere

Explanation:

Analyze weathering interactions

The first question asks which Earth systems impact weathering in the geosphere. Weathering is the breakdown of rock material.

• The biosphere impacts weathering through plant roots physically wedging rocks apart and organic acids chemically breaking them down.
• The atmosphere impacts weathering by producing acid rain (chemical weathering).
• The hydrosphere impacts weathering through water dissolving minerals or physically breaking rocks (frost wedging, river erosion).

Therefore, all of these systems impact weathering, making "All of these Earth systems impact the rate of weathering in the geosphere" the correct choice. This demonstrates Earth Systems and Weathering Processes interactions.

Analyze resource sustainability

The second question asks why resource sustainability and conservation are important considerations regarding Earth's systemic nature.

• Earth systems are interconnected; changes in one system affect others.
• Resources are finite, and living things depend on them.
• Ensuring sustainability and conservation helps maintain the proper functioning and balance of the interconnected Earth systems.

Thus, the correct choice is "Resource sustainability and conservation help to ensure the Earth system continues to function properly."

Analyze biosphere interactions

The third question asks how the biosphere works within the Earth system.

• The biosphere consists of all living organisms.
• Living things do not exist in isolation; they constantly interact with and are influenced by the physical environment.
• The biosphere is impacted and influenced by the hydrosphere (water), geosphere (land/soil), and atmosphere (air).

This highlights Biosphere Interactions within the broader Earth Systems, making "the biosphere is impacted and influenced by the hydrosphere, geosphere, and atmosphere" the correct choice.

Answer:

Question 1

• The biosphere, through the work of plants, could physically and chemically change the rock material.
• All of these Earth systems impact the rate of weathering in the geosphere. (Correct answer)
• The atmosphere impacts weathering by producing acid rain that could alter the rock material.
• The hydrosphere impacts weathering by producing water dissolving and or physically breaking the rock material.

Question 2

• Resources availability in one Earth system will not impact other Earth systems.
• Resource sustainability and conservation help to ensure the Earth system continues to function properly. (Correct answer)
• The resources of the Earth system are unlimited and do not require conservation.
• Living things on Earth do not depend on resources for survival.

Question 3

• the biosphere only impacts the atmosphere
• the biosphere is influenced by the geosphere and atmosphere
• the biosphere is impacted and influenced by the hydrosphere, geosphere, and atmosphere (Correct answer)
• the biosphere is impacted only by the hydrosphere
