Question

Mars's atmosphere is divided into layers including the troposphere, mesosphere, thermosphere, etc. The thermosphere is the layer that is furthest from Mars's surface. The distance from Mars and the thermosphere's temperature have a positive association. Interpret the meaning of the positive association with respect to the temperature.

Group of answer choices
As you move closer to Mars, the temperature increases.
As you move away from Mars, the temperature increases.
As you move away from Mars, the temperature decreases.
As you move away from Mars, the temperature remains the same.
As you move closer to Mars, the temperature remains the same.

Answer 1

(B)As you move away from Mars, the temperature increases.

Explanation:

I took the test and got it right :)

Answer 2

(B)As you move away from Mars, the temperature increases.

Explanation:

Definition

Two variables have a positive/direct association if an increase in the value of one variable lead to an increase in the value of the other variable. Similarly, a decrease in the value of one variable will lead to a decrease in the value of the other variable.

The distance from Mars and the thermosphere's temperature have a positive association.

Therefore, by definition of positive association:

• When the distance increases, the thermosphere's temperature increases.
• When the distance decreases, the thermosphere's temperature decreases.

The correct option is B
