Astronomy Flashcardizz Review

Front

What is the Winter Solstice?

Back

The Winter Solstice is the shortest day of the year, occurring when the Earth's tilt is farthest away from the Sun, resulting in less sunlight in the Northern Hemisphere.

Front

What is the Summer Solstice?

Back

The Summer Solstice is the longest day of the year, occurring when the Earth's tilt is closest to the Sun, resulting in more sunlight in the Northern Hemisphere.

Front

What happens during the equinoxes?

Back

During the equinoxes, day and night are approximately equal in length, and each hemisphere receives the same amount of sunlight.

Front

What causes Earth's seasons?

Back

Earth's seasons are caused by the tilt of the Earth on its axis, which affects the angle and intensity of sunlight received in different regions.

Front

What are tides?

Back

Tides are the rise and fall of sea levels caused by the gravitational pull of the Moon and the Sun on Earth.

Front

What is the role of the Moon's gravity on Earth?

Back

The Moon's gravity affects Earth by causing tides, which are the periodic rise and fall of ocean levels.

Front

What is the significance of the Earth's axial tilt?

Back

The Earth's axial tilt is significant because it determines the intensity and distribution of sunlight, leading to seasonal changes.

Front

What is an equinox?

Back

An equinox is an event in which the plane of Earth's equator passes through the center of the Sun, resulting in equal day and night.

Front

How does the distance between the Earth and the Sun affect seasons?

Back

The distance between the Earth and the Sun does not significantly affect seasons; seasons are primarily caused by the tilt of the Earth's axis.

Front

What is the difference between a solstice and an equinox?

Back

A solstice marks the longest or shortest day of the year, while an equinox marks the time when day and night are of equal length.
