Science Common Assessment #2: Study Guide

Front

What is a total solar eclipse?

Back

A total solar eclipse occurs when the Moon completely covers the Sun, blocking all direct sunlight and turning day into darkness.

Front

What is a lunar eclipse?

Back

A lunar eclipse happens when the Earth comes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

Front

What causes seasons on Earth?

Back

Seasons are caused by the tilt of the Earth's axis and its orbit around the Sun, leading to varying angles of sunlight at different times of the year.

Front

What is the difference between a total and partial eclipse?

Back

In a total eclipse, the celestial body is completely covered, while in a partial eclipse, only a part of the celestial body is obscured.

Front

What is the role of the Sun in weather patterns?

Back

The Sun heats the Earth's surface, causing air to warm and rise, which leads to the formation of weather patterns.

Front

What happens during a lunar eclipse?

Back

During a lunar eclipse, the Earth blocks sunlight from reaching the Moon, causing the Moon to appear darkened or reddish.

Front

What is the significance of the Earth's tilt?

Back

The tilt of the Earth (about 23.5 degrees) is crucial for creating seasons, as it affects how sunlight is distributed across the planet.

Front

What is a celestial object?

Back

A celestial object is any natural object outside of Earth's atmosphere, such as stars, planets, moons, and asteroids.

Front

What is the shadow of a celestial object?

Back

The shadow of a celestial object is the area where light from a light source (like the Sun) is blocked by that object.

Front

What is the difference between the Northern and Southern Hemispheres?

Back

The Northern Hemisphere is the half of Earth that is north of the equator, while the Southern Hemisphere is south of the equator, leading to opposite seasons.
