Seasons and Tides Flashcards

Front

When is it fall/autumn in the Northern Hemisphere?

Back

B
At A, the Northern Hemisphere is tilted towards the sun, so this would be summer in the Northern Hemisphere.
Point B comes after point A (follow the arrows), and Fall comes after Summer, so point B is Fall in the Northern Hemisphere.

Front

When is it spring in the Northern Hemisphere?

Back

D

At C, the Northern Hemisphere is tilted away from the sun, so this would be winter in the Northern Hemisphere.
Point D comes after point C (follow the arrows), and Spring comes after Winter, so point D is Spring in the Northern Hemisphere.

Front

When is it winter in the Northern Hemisphere?

Back

C

At C, the Northern Hemisphere is tilted away from the sun, so this would be winter in the Northern Hemisphere.
At point C, the sun's rays are more directly pointed at the Southern Hemisphere--it would be hotter there. The Northern Hemisphere does not get as many direct rays when it is tilted away from the sun.

Front

When is it summer in the Northern Hemisphere?

Back

A
At point A, the Northern Hemisphere is tilted towards the sun. The Northern Hemisphere would receive rays that are more direct and intense. The Northern Hemisphere would be hotter than the Southern Hemisphere at this point, so the Northern Hemisphere would have summer.

Front

In position C, which hemisphere is tilted towards the sun?

Back

Southern Hemisphere

Front

At point C, which hemisphere has shorter daylight hours?

Back

Northern Hemisphere because it is tilted away from the sun.

When the Earth is tilted away from the sun, the sun's rays don't reach the north pole as much, thus the daylight hours, or the times when you can see the sun in the Northern Hemisphere, are much shorter.

Front

At point C, which hemisphere has longer daylight hours?

Back

Southern Hemisphere because it is tilted toward the sun
When the Earth is tilted away from the sun, the Southern Hemisphere gets more of the direct rays from the sun--even in the South Pole! Thus, the Southern Hemisphere would have longer daylight hours at point C.

Front

Is it possible to have a High Tide and a Low Tide on the same day?

Back

Yes

There are generally 2 High Tides and 2 Low Tides in one day.

Front

The imaginary line around which Earth rotates is called the ___.

Back

Axis

Front

What has the greatest effect on the tides?

Back

The Moon

The moon is closer to Earth and that is why its gravitational pull has the greatest effect.

Distance and mass are the things that affect gravity the most.
