Which of the following best describes the difference between weather and climate?

• Weather refers to short-term atmospheric events, while climate refers to long-term average weather patterns.

• Weather is the same as climate and both refer to daily conditions.

• Climate refers to short-term changes, while weather refers to long-term averages.

• Weather and climate are unrelated concepts.

One of your friends added chocolate chips to some popcorn. When the chocolate chips touched the hot popcorn, they melted because of (a)   .

• Conduction
• Convection
• Radiation

Answer explanation

When the chocolate chips touched the hot popcorn, they melted due to conduction. Conduction is the transfer of heat between two objects in direct contact, in this case, the hot popcorn and the chocolate chips. The heat from the popcorn is transferred to the chocolate chips, causing them to melt.

Why do areas near the equator receive more direct solar radiation than areas near the poles?

• Because the sun's rays hit the equator at a more direct angle

• Because the equator is closer to the sun

• Because the poles have more clouds

• Because the earth spins faster at the equator
