Question

question 4.
consider the data about the temperature ranges on earth to answer the question below.
how does earth’s position relative to the sun, along with its atmosphere, support the existence of liquid water?
a. earth’s distance from the sun allows for a stable climate where liquid water can exist, and the atmosphere traps heat to prevent the water from freezing
b. earth is located close enough to the sun to ensure that water remains in liquid form, while its atmosphere blocks most heat, causing the water to evaporate.
c. earth’s proximity to the sun causes temperatures to be too high for liquid water to exist, but the atmosphere keeps it in a gaseous state.
d. earth’s orbit around the sun causes dramatic shifts in temperature, which helps maintain the water cycle and supports life by regulating water availability.

Explanation:

To solve this, we analyze each option:

• Option A: Earth's distance from the Sun (the habitable zone) provides a stable temperature range for liquid water. The atmosphere (like greenhouse gases) traps heat, preventing freezing. This matches scientific understanding.
• Option B: If Earth were too close, temperatures would be too high (water would vaporize), and the atmosphere blocking most heat would cool it, not cause evaporation. Incorrect.
• Option C: Earth's proximity isn't too high; liquid water exists. The atmosphere doesn't keep water gaseous; it helps retain heat for liquid. Incorrect.
• Option D: Earth's orbit (nearly circular) has minimal temperature shifts. Dramatic shifts would disrupt liquid water. Incorrect.

Answer:

A. Earth’s distance from the Sun allows for a stable climate where liquid water can exist, and the atmosphere traps heat to prevent the water from freezing
