Question

Two factors which cause global climate change are listed below.

Factor 1: Changes in the shape of Earth's orbit.
Factor 2: Changes in the amount of Sun's heat received by the Earth's atmosphere and surface.

Which of these statements is correct about the two factors which cause global climate change?

Select one:
a. Both are natural factors.
b. Both are human induced factors.
c. Factor 1 is a natural factor and Factor 2 is a human induced factor.
d. Factor 2 is a natural factor and Factor 1 is a human induced factor.

Answer 1

I believe the answer is c. Factor 1 is a natural factor and Factor 2 is a human induced factor.
The amount of heat received by the sun has increased because of the amount of CO2 which human expelled to the atmosphere.
Because of this CO2, the heat from the sun couldn't be reflected outside the atmosphere and trapped within the earth.

Answer 2

Answer:

A) Both are natural factors

Explanation:

For factor 1, humans can't control the shape of Earth's orbit. For Factor 2, humans can't cause the amount of heat received by our planet's atmosphere and surface. The question NEVER implies or explicitly states if it were due to humans because of pollution. It just talks about the amount of heat we receive.
