EARTH'S ROTATION AND REVOLUTION

The Northern Hemisphere receives more solar energy during one half of the year than the other half. Why is this happening?

• The angle at which sunshine hits the Northern Hemisphere changes.

• The distance of the Northern Hemisphere from the sun stays the same.

• Earth's tilt changes angles.

• More energy is produced by the sun.

Which of the following is common in winter, but not summer?

• warmer temperatures

• more direct rays of the sun strike the Earth

• shorter days

• shorter nights

Which direction does the Earth spin as seen from the North Pole?

• clockwise

• counter clockwise

• north to south

• south to north

Were does the sun seem to rise...and set?

• The sun rises in the west and sets in the east.

• The sun rises in the north and sets in the south.

• The sun rises in the south and sets in the north.

• the sun rises in the east and sets in the west.

What is a season?

• The time it takes for Earth to spin one time on its axis.

• The time it takes Earth to revolve around the sun.

• A time of the year with similar weather conditions.

• The time between the two solstices.

When the North Pole is tilted toward the sun at its maximum point , what day is it in the Northern Hemisphere?

• The Winter Solstice

• The Summer Solstice

• The Spring Equinox

• The Fall Equinox

When the North Pole is tilted toward the sun, it is...

• winter in the Southern Hemisphere.

• summer in the Southern Hemisphere.

What two days of the year do the Northern and Southern Hemispheres receive 12 hours of daylight and nighttime?

• The spring and fall solstices

• The spring and fall equinoxes.

• The first day of summer and winter.

Why does the Earth have seasons?

• Earth's Equator is tilted.

• Earth's solstice is tilted.
