Which best explain the changes in the seasons?

• Seasons change as a result of high temperatures caused by Earth's tilt and revolution around the sun.

• Seasons change as light from the sun hits atmosphere and as Earth rotates around the sun.

• Season change as a result of the temperature the creasing because of Earth's revolution around the sun.

• Seasons change due to the amount of sunlight hitting Earth and Earth's tilt as it revolves around the sun.

The students is instructed to illustrate this information in a notebook. How will the student illustrate winter in the Northern Hemisphere?

• Earth's Northern hemisphere will tilt away from the sun

• Earth's Northern hemisphere will tilt toward the sun

• Earth's Southern hemisphere will tilt away from the sun

• Earth's orbit will be farther away from the sun

Answer explanation

It is Summer in the Northern hemisphere when the Earth tilts toward the sun, so the opposite is correct. When the earth tilts away from the sun, then it is winter in the Northern hemisphere.

Early scientists believed the sun revolved around Earth. What do modern scientists believe about the revolution of the sun and Earth?

• Earth revolves around the sun, causing day and night.

• Earth revolves around the sun, causing seasons, as well as day and night.

• Earth revolves around the sun on a tilted axis, causing a change in seasons, and Earth rotates on its axis, causing day and night.

• Earth revolves around the sun, causing day and night, and Earth rotates on its axis, causing a change in seasons.
