What causes the variation in daylight hours between locations in the Northern Hemisphere?

Back

The variation in daylight hours is caused by the tilt of the Earth's axis. When the Northern Hemisphere is tilted toward the sun, it experiences longer daylight hours, while when it is tilted away, it experiences shorter daylight hours.

Front

What is the significance of the Northern Hemisphere experiencing winter?

Back

When the Northern Hemisphere experiences winter, it is tilted away from the sun, resulting in shorter days and lower temperatures.

Front

How can you determine which location is experiencing day or night based on a diagram?

Back

You can determine day and night by identifying which side of the Earth is facing the sun (day) and which side is in shadow (night).

Front

What is a warm front?

Back

A warm front is a boundary where warm air moves in and replaces cooler air. It is typically associated with gradual temperature increases and precipitation.

Front

What happens to warm air in convection?

Back

In convection, warm air rises because it is less dense than cooler air.

Front

What is the difference between a cold front and a warm front?

Back

A cold front occurs when cold air pushes into a region of warm air, causing abrupt weather changes, while a warm front occurs when warm air rises over cold air, leading to gradual weather changes.

Front

What is the role of the Earth's tilt in seasonal changes?

Back

The Earth's tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

Front

What is the definition of convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

How does the position of the sun affect the length of daylight?

Back

The position of the sun in the sky changes throughout the year due to the Earth's tilt and orbit, affecting the length of daylight experienced at different locations.

Front

What is the significance of the equator in terms of daylight hours?

Back

The equator experiences relatively consistent daylight hours throughout the year, as it is not significantly affected by the tilt of the Earth's axis.
