Question

4 multiple choice 20 points
how does the hydrosphere impact the atmosphere?
water evaporates from oceans and then falls back to the planet as precipitation
water is an agent of erosion and moves sediment over the surface of the earth
water moves throughout the water cycle, changing form, as it travels all over the planet
water is consumed by living organisms for survival

5 multiple choice 20 points
which of the statements is true for the earth system?
only a few parts of the earth system interact with each other.
all parts of the earth system are interconnected and interdependent. if one part of the earth system is changed, it will impact all other parts.
the earth system is very simple and lacks complexity.

Explanation:

Analyze Question 4

The question asks how the hydrosphere (all water on Earth) impacts the atmosphere (the envelope of gases surrounding Earth). Let's evaluate the options:

• Option 1: "water evaporates from oceans and then falls back to the planet as precipitation" describes the direct exchange of water vapor and heat between the hydrosphere and the atmosphere, which is a key interaction.
• Option 2: "water is an agent of erosion and moves sediment over the surface of the earth" describes the interaction between the hydrosphere and the geosphere.
• Option 3: "water moves throughout the water cycle, changing form, as it travels all over the planet" is a general description of the water cycle but does not specifically focus on the impact on the atmosphere.
• Option 4: "water is consumed by living organisms for survival" describes the interaction between the hydrosphere and the biosphere.

Therefore, the first option is the correct choice.

Analyze Question 5

The question asks which statement is true for the Earth system. Let's evaluate the options:

• Option 1: "Only a few parts of the Earth system interact with each other." This is incorrect because the Earth system is highly integrated.
• Option 2: "All parts of the Earth system are interconnected and interdependent. If one part of the Earth system is changed, it will impact all other parts." This is a fundamental concept of Earth Systems science, describing how spheres (atmosphere, biosphere, hydrosphere, geosphere) are deeply interconnected.
• Option 3: "The Earth system is very simple and lacks complexity." This is incorrect because the Earth system is highly complex.

Therefore, the second option is the correct choice.

Answer:

Question 4

• (A) water evaporates from oceans and then falls back to the planet as precipitation (Correct answer)
• (B) water is an agent of erosion and moves sediment over the surface of the earth
• (C) water moves throughout the water cycle, changing form, as it travels all over the planet
• (D) water is consumed by living organisms for survival

Question 5

• (A) Only a few parts of the Earth system interact with each other.
• (B) All parts of the Earth system are interconnected and interdependent. If one part of the Earth system is changed, it will impact all other parts. (Correct answer)
• (C) The Earth system is very simple and lacks complexity.
