100

These lines are used to measure the distance (by angle) east and west on earth.

Longitude

100

The ocean levels are higher on the sides of the earth on the same side and opposite side of the earth relative to the location of the moon.

High Tide

100

The moon is between the sun and earth and the umbra of the moon's shadow hit's the earth in one location.  The sun appears dark.

Total Solar Eclipse

100

This is where the sun hits at its zenith at noon on the summer solstice.

Tropic of Cancer

100

This is located at 0 degrees latitude.

Equator

200

These lines are used to indicate position (by angle) north and south on the celestial sphere.

Declination

200

Ocean levels are lower on the sides of the earth that are at 90 degrees relative to the location of the moon?

Low Tide

200

The moon is located between the earth and the sun and is in the part of its orbit further from the earth.  The umbra of the moon's shadow hits the earth and the sun appears dark, with a ring of light visible around the outside.

Annular Solar Eclipse

200

This is where the sun hits at its zenith on the winter solstice.

Tropic of Capricorn

200

In the southern hemisphere, what month has the shortest days?

June

300

This line is at 0 degrees longitude.

Prime Meridian

300

The tide occurs when the sun and moon are at 90 degrees during the first quarter and third quarter phases of the moon and causes a lower tide.

Neap Tide

300

The earth is between the moon and the sun and the earth's shadow hits the moon, causing it to appear red.

Lunar Eclipse

300

Why is it warmer in the summer than in the winter?

The earth receives more direct sunlight due to the tilt of the earth at the hemisphere that is in summer. 

300

During this lunar phase, the moon appears dark and is on the same side of the earth as the sun.

New moon

400

These lines are used to measure the position (by angle) east and west on the celestial sphere.

Right ascension

400

This tide occurs when the sun and moon are parallel  during the full moon phase of the moon and creates a higher tide.

Spring Tide

400

The moon is between the sun and the earth. The penumbra of the moon lines up with the earth, causing part of the sun to be covered/appear black.

Partial Solar Eclipse

400

How does the sun's apparent path of the sun change with the season?

The sun appears higher in the sky and is above the horizon longer in the summer.  The sun appears lower in the sky and is above the horizon less time in the winter.

400

The time based on the earth's rotation that is constant.

Mean solar time.

500

These lines indicate the distance (by angle) north and south on the earth.

Latitude

500

What causes the ocean tides on earth to change?

The gravitational pull of the moon causes water to bulge out on the sides of the earth parallel to the moon (high tides) and the sides of the moon perpendicular to the moon to have lower water levels (low tides).  The earth rotates through these water levels (tides).

500

This type of eclipse can be seen from one hemisphere (half of the earth) at a time.

Lunar eclipse

500

How do we know that the earth's seasons are not due to the distance of the earth from the sun?

1. The change in distance between the earth an sun is not enough to cause a change in temperature. 2. The seasons would not be different in each hemisphere. 3. The earth is closest to the sun in January.

500

The time that is measured based on the position of the sun in the sky.
