Answer:

Independent variable is that which we change or manipulate.

Explanation:

By changing the independent variable, there is a corresponding change in the dependant variable which we intend to measure.

Answer:

The dependant variable is the one you measure. The dependant variable depends on how you change the independent variable.

Explanation: For example we want to observe speed of a car change with respect to time.

Here, time is the independent variable as it has its own pace regardless of the car. However, at different instances of time , the car has different speeds. Thus, the speed of the car is the dependant variable as it depends on time.

Which of the following terms describes the movement of water from the surface to the atmosphere?

lukranit [14]

Answer:

The answer is evaporation.

Explanation:

Runoff is not right because runoff is water that hits the surface of the earth, then runs down into natural bodies of water. It is not condensation either. That is because condensation is when cool water vapor comes into contact with humid, warm air causes water droplets to appear on the surface of what is containing the cool water vapor. Finally, precipitation is when water comes down from the atmosphere to the surface of the earth, therefore this is incorrect. Evaporation however is when water from the surface of the earth turns into water vapor and goes into the atmosphere. Therefore it is the right answer.
