Seasons

What does the rotation of the earth cause us to experience?

• Seasons

• Day and night

• Year

• Summer

Answer explanation

The rotation of the Earth on its axis causes us to experience day and night. As the Earth spins, different parts face the Sun, resulting in daylight, while the opposite side experiences darkness.

The Earth tilts at ______

• 90°

• 23.5°

• 56.2°

• 24°

Answer explanation

The Earth tilts at an angle of 23.5°, which is responsible for the changing seasons. This tilt is crucial for the variation in sunlight received at different latitudes throughout the year.

What is the term used to describe the motion of the Earth around the Sun?

• Resolution

• Rotation

• Revolution

• Round

Answer explanation

The term 'revolution' refers to the Earth's motion around the Sun, completing one full orbit approximately every 365.25 days. This distinguishes it from 'rotation', which describes the Earth's spin on its axis.

Why is the Equator warmest?

• Because it is closest to the sun.

• Because it receives the most direct sunlight

• Because no clouds form here.

• Because it is far from the sun

Answer explanation

The Equator is warmest because it receives the most direct sunlight throughout the year. This direct exposure leads to higher temperatures compared to other regions that receive sunlight at an angle.

Which of the following best describes the tilt of the earth when it is summer in the southern hemisphere?

• The northern hemisphere is tilted toward the sun

• The northern hemisphere is tilted away from the sun

• The southern hemisphere is tilted toward the sun

• The southern hemisphere is tilted away from the sun

Answer explanation

During summer in the southern hemisphere, that hemisphere is tilted toward the sun, receiving more direct sunlight and warmth. Therefore, the correct choice is that the southern hemisphere is tilted toward the sun.

What effect does the tilt of the earth have?

• It causes the earth to be farther away from the sun at different times of the year

• It changes the angle that the sun strikes the earth in different land areas

• When the earth is tilted away from the sun we have day

• When the earth is tilted away from the sun we have night

Answer explanation

The tilt of the Earth affects how sunlight strikes different areas, leading to variations in temperature and seasons. This is why the correct answer is that it changes the angle that the sun strikes the earth in different land areas.

What season is it in the Northern Hemisphere when it is fall in the Southern Hemisphere?

• Winter

• Spring

• Summer

• Fall

Answer explanation

When it is fall in the Southern Hemisphere, the Northern Hemisphere experiences spring. This is due to the tilt of the Earth, causing opposite seasons in the two hemispheres.

One rotation of Earth is equal to _____

• a year

• a day

Answer explanation

One rotation of Earth on its axis takes approximately 24 hours, which defines a day. Therefore, one rotation of Earth is equal to a day, not a year.

What happens when the area in which you live tilts away from the sun?

• It is winter

• It is summer

• It is spring

• It is fall

Answer explanation

When the area you live in tilts away from the sun, it receives less direct sunlight, leading to colder temperatures. This phenomenon is characteristic of winter, making 'It is winter' the correct answer.

What does it take the Earth one year to complete?

• tilting its axis north or south

• a revolution around the sun

• receiving energy from the sun

• a rotation around its axis

Answer explanation

The Earth takes one year to complete a revolution around the sun, which defines the length of a year. Other options describe different processes, but only a revolution around the sun directly relates to the time frame of a year.
