Earth's Role in Space

There are four seasons on Earth (summer, autumn, winter, and spring). Which of the following is the reason Earth experiences seasons?

• Earth's revolution around the Sun takes one year. The motion causes Earth to experience seasons.

• Earth's tilt causes different areas of the Earth’s surface to get different amounts of daylight at different times of the year.

• The Earth experiences winter in all places when it is closest to the Sun.

• The seasons are due to the rotating on the axis. This rotation causes darkness on one side thus have winter we it is in darkness.

Kepler's 3rd laws explains which of the following?

• Planets further from the sun have an orbit that lasts MUCH longer than planets that are close to the sun

• Planets further from the sun have an orbit that lasts MUCH shorter than planets that are close to the sun

• Planets further from the sun have an orbit that lasts same time as planets that are close to the sun

• The reason the Earth experience seasons.

A larger-than-normal height difference between low tide and high tide most likely occurs when

• he sun, moon, and Earth are perpendicular to each other.

• the moon is in first quarter.

• the sun, moon, and Earth are aligned in a relatively straight line.

• Earth is in perhelion.

Changes of the seasons are a direct result of
