8.7A Revolution Mini Flashcard #3

Front

What causes the seasons on Earth?

Back

The seasons are caused by Earth's revolution around the Sun and its tilted axis.

Front

What is the tilt of the Earth's axis?

Back

The Earth's axis is tilted at an angle of approximately 23.5 degrees.

Front

Why does summer start in different months in North and South America?

Back

Summer starts in different months due to the tilt of the Earth, which affects the amount of sunlight each hemisphere receives.

Front

What would happen if the Earth had no tilt?

Back

If the Earth had no tilt, there would be no seasons.

Front

How does the Earth's revolution affect daylight hours?

Back

The Earth's revolution around the Sun changes the angle of sunlight, affecting the length of daylight hours in different locations.

Front

What is the significance of the equator in relation to seasons?

Back

The equator experiences relatively consistent daylight hours and temperatures throughout the year, unlike the poles.

Front

What happens during the summer solstice in the Northern Hemisphere?

Back

During the summer solstice, the Northern Hemisphere is tilted toward the Sun, resulting in the longest day of the year.

Front

What is the winter solstice?

Back

The winter solstice occurs when the Northern Hemisphere is tilted away from the Sun, resulting in the shortest day of the year.

Front

How do daylight hours differ between the Northern and Southern Hemispheres?

Back

When one hemisphere experiences summer with longer daylight hours, the other hemisphere experiences winter with shorter daylight hours.

Front

What is the role of the Sun in Earth's seasons?

Back

The Sun provides the energy that drives the seasons through its varying angles of sunlight due to Earth's tilt and revolution.
