Does one hemisphere receive more incoming solar energy during its summer?

Back

Yes, the Earth gets more solar energy in the Southern Hemisphere's summer because it's closer to the Sun

Which statement best explains the seasonal differences between the Northern and Southern Hemispheres?

Back

The Northern Hemisphere has colder winters due to more land, which loses heat quickly.

Answer explanation

The Northern Hemisphere has more land, while the Southern Hemisphere has more water. Water heats up and cools down more slowly than land, so:

• The Northern Hemisphere has colder winters because the land loses heat quickly.

• The Southern Hemisphere has warmer summers because it’s closer to the Sun during its summer.

How does the Earth’s tilt cause the seasons to change?

Back

The tilt of the Earth causes different hemispheres to receive varying amounts of sunlight, resulting in the changing seasons.

Answer explanation

• When a hemisphere is tilted toward the Sun, it gets more direct sunlight, making it warmer (summer).

• When a hemisphere is tilted away from the Sun, it gets less sunlight, making it colder (winter).

This tilt is why we have seasons!

What causes seasonal changes?

Back

The tilt of the Earth's axis and its spherical shape orbiting around the Sun.

Answer explanation

Seasonal changes are caused by the tilt of the Earth's axis (23.5°) and its orbit around the Sun.

• As the Earth moves around the Sun, different parts of the planet are tilted toward or away from the Sun.

• When a hemisphere is tilted toward the Sun, it gets more direct sunlight (summer).

• When it’s tilted away, it gets less sunlight (winter)

How does solar energy vary by latitude?

Back

The Equator receives more solar energy because sunlight is more direct there.

Answer explanation

• Near the Equator, sunlight is more direct and concentrated, so these areas receive more solar energy year-round.

• Toward the poles, sunlight hits at a lower angle, spreading out over a larger area, so these regions receive less solar energy and are colder.

This variation in solar energy causes differences in temperature and climate across latitudes.

How can different areas of one continent have such different temperatures?

Back

Temperature variations across a continent are influenced by latitude, altitude, ocean proximity, and prevailing winds.

Answer explanation

• Latitude: Areas closer to the Equator are warmer, while areas farther away are cooler.

• Elevation: Higher elevations (like mountains) are colder than lower areas.

• Proximity to Water: Coastal areas are milder because water heats and cools slowly, while inland areas have more extreme temperatures.

• Ocean Currents: Warm or cold ocean currents can influence nearby land temperatures.

• Wind Patterns: Winds can carry hot or cold air to different regions.

Why is air colder at high altitudes?

Back

Air expands and cools because there is less pressure and the air molecules will collide less.
