Question

question 5 (multiple choice worth 3 points)
two factors which cause global climate change are listed below.
factor 1: habitat loss
factor 2: earth’s axial tilt
which of these statements is correct about the two factors which cause global climate change?

• factor 1 and factor 2 are considered natural factors.
• factor 1 and factor 2 are considered human - induced factors.
• factor 1 is a natural and a human - induced factor, and factor 2 is a natural factor.
• factor 1 is a natural factor, and factor 2 is a human - induced factor.

question 6 (multiple choice worth 3 points)
heat moves through the atmosphere through the process of

• convection
• conduction
• radiation
• refraction

Explanation:

Question 5

• Habitat loss (Factor 1) can be caused by natural (e.g., natural disasters) and human - induced (e.g., deforestation) factors. Earth’s axial tilt (Factor 2) is a natural, long - term astronomical factor. So the correct statement is "Factor 1 is a natural and a human - induced factor, and Factor 2 is a natural factor."

• Convection is the transfer of heat by the movement of fluid (like air in the atmosphere) masses. Conduction needs direct contact (not common in atmosphere), radiation is heat transfer via electromagnetic waves (e.g., from Sun), and refraction is about light bending. Heat in the atmosphere moves mainly by convection.

Answer:

Factor 1 is a natural and a human - induced factor, and Factor 2 is a natural factor.
