Why does the Earth experience unequal heating?

• The oceans are not equally distributed around the Earth.

• The Earth's revolution brings it closer to the Sun at certain points during the year.

• The curvature of Earth.

• The atmosphere is not equally distributed around the Earth.

• direct

• indirect

Where on Earth receives the LEAST intense sunlight?

• The north and south pole

• The equator

• All areas get the same light

Answer explanation

🥶 Because places away from the equator do not face the Sun directly, sunrays are LESS intense and temperatures are LOWER 🥶

At latitudes near the North Pole and South Pole, sunlight strikes Earth's surface at a low angle. This causes which effect?

• The poles receive more energy than anywhere else on Earth.

• There is more sunlight per unit of surface area.

• Santa must use lights all day and night in the North Pole from June to September.

• The poles receive very little energy per unit of surface area.

The area of Earth that receives the most solar radiation is the equator. Why?

• Sunlight reflects off water more powerfully at the equator.

• Near the equator, sunlight strikes Earth's surface at a low angle.

• In latitudes near the equator, sunlight strikes Earth's Surface at a nearly 90 degree angle year round.

A map of sea surface temperatures is provided. The patterns that are observed are due to the fact that

• the earth is wider at the equator, so this area spins faster than the poles.

• the equator receives more of the Sun's radiation than other parts of the Earth.

• the salt content is greater at the poles than at the equator.

• the warm, less dense water near the equator sinks, while the colder water rises.

Which of the following is true about the heating of land and water?

• During the day, the Sun's energy heats up the land faster, which makes the air above it warmer.

• During the day, the Sun's energy heats up the water faster, which makes the air above it warmer.

• At night, the land cools off slower, making the air above it warmer.

• At night, the water cools off slower, making the air above it cooler.
