Unit 4: Earth and Moon Exam

Front

What is the tilt of the Earth and why is it important?

Back

The tilt of the Earth is approximately 23.5 degrees. It is important because it affects the angle and intensity of sunlight received at different latitudes, leading to the changing seasons.

Front

What causes the change in length of day and night throughout the year?

Back

The change in length of day and night is caused by the tilt of the Earth's axis and its orbit around the Sun, which affects how much sunlight each hemisphere receives.

Front

What is the significance of the Earth's elliptical orbit?

Back

The Earth's elliptical orbit means that the distance from the Sun varies throughout the year, which can slightly affect the intensity of seasons but is not the primary cause of seasonal changes.

Front

How does the tilt of the Earth affect seasonal weather patterns?

Back

The tilt of the Earth causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to seasonal weather patterns such as summer and winter.

Front

What is the lunar cycle?

Back

The lunar cycle is the sequence of phases the Moon goes through as it orbits the Earth, including new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

Front

How does the Sun influence the phases of the Moon?

Back

The Sun illuminates the Moon, and as the Moon orbits the Earth, the angle between the Earth, Moon, and Sun changes, causing the different phases of the Moon.

Front

What is the relationship between the Earth's tilt and the equinoxes?

Back

The equinoxes occur when the tilt of the Earth's axis is such that the Sun is directly above the equator, resulting in nearly equal day and night lengths across the globe.

Front

What happens during the summer solstice in the Northern Hemisphere?

Back

During the summer solstice, the Northern Hemisphere is tilted closest to the Sun, resulting in the longest day of the year and the start of summer.

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 and the start of winter.

Front

How do the positions of the Earth and Sun affect climate?

Back

The positions of the Earth and Sun affect climate by determining the amount of solar energy received at different locations, influencing temperature, precipitation, and seasonal changes.
