Unit 3 Test Review Tides/phases of moon/eclipses

Tides

• Daily rise and fall of Earth's water on its' coastlines

• High tides: water at highest point

• Low tides water at lowest point

• Gravitation pull from Moon and Sun

Multiple Choice

What are tides?

• Tides occur because the comet Neowise passed by Earth

• The daily rise and fall of Earth's waters on its coastlines.

• The yearly rise and fall of Earth's water on its coastlines.

• Tides occur because Jupiter is in alignment with Saturn

Multiple Choice

The _______ pulls on the water facing the moon creating a __________.

• gravitational force, low tide

• low tide, gravitational force

• tidal bulge, gravitational force

• gravitational force, tidal bulge

Spring Tides

• Highest of the high tides and lowest of the low tides. 

• Moon, Sun, and Earth are aligned 

• The Moon and Sun's gravitational pull works together 

• Occurs twice a month 

Neap Tides

• Lower high tides and Higher low tides 

• Moon and Sun are at right angles to the Earth 

• Gravity of the Sun and Moon work against each other

Rotation vs revolution

• Rotation is when an object spins around its axis.

• Revolution is when an object travels in a path around another.

Vocab.

• Axis- an imaginary line that runs through the North and South Pole. It is tilted at 23.5 degrees 

• Elliptical: Earth's orbital path is slightly oval shaped. 

• Orbit: The path an object in space takes as it goes around another object. 

• Heliocentric model: A model that consists of the planets orbiting the Sun.

Describe rotation and revolution

• Rotation is when an object travels in a path around another.

• Revolution is when an object travels in a path around another.

• Rotation is when an object spins around its axis.

• Revolution is when an object spins around its axis.

Multiple Choice

Earth's revolution causes day and night.

• True

• False

Vocab.

• Season:  The tilt and revolution of the earth as it moves around the sun cause

• Summer Solstice: The earth is in a position so that the North Pole is tilted most directly toward the sun.

• Equinoxes: Days and nights are equal length, and the noon sun is directly overhead.

• Winter Solstice: This is the day of the year with the least amount of daylight, which is due to the tilt of the earth's axis.

Multiple Choice

Why is it warmer in the summer?

• The earth's axis does not have a tilt

• The rotation of Earth

• The tilt of the earth's axis away from the sun allows those parts of the earth to have more sunlight.

• The tilt of the earth's axis towards the sun allows those parts of the earth to have more direct sunlight.

Moon

• Spring tides: New moon Full moon

• Neap tides: First Quarter, Third Quarter

• Moons rotation = Moons revolution--see 1 side

• Phases: moon revolves around Earth reflecting light from Sun

Multiple Choice

What causes the phases of the moon?

• As the moon revolves around Earth reflecting light from the sun, some, all, or none of the moon can be seen in the different phases of the moon

• the moon revolves around the Earth none of the light from is reflected

• the moon revolves around the Earth, it revolves around Jupiter

• none of the choices

Vocab.

• Penumbra: The outer, larger, lighter shadow

• Umbra : the fully shaded inner region of a shadow 

• Corona: During a solar eclipse, the moon covers the sun, a small ring of fire is visible around the edge 

• Eclipse: darkening of a planet, moon, or other object in space by the shadow of another object in space 

Lunar Eclipse

• The moon turns dark

• Light from the sun is blocked

• Earth is directly between the moon and sun

• Earth casts its shadow on the moon 

Solar Eclipse

• Moon moves between the sun and Earth 

• The moon blocks out the light of the sun and casts a shadow onto the Earth 

Multiple Choice

An eclipse occurs when the light from the sun or moon is reflected because another body (such as the moon or Earth) comes in alignment.

• True

• False

Multiple Choice

What is the difference between a lunar eclipse and a solar eclipse?

• A solar eclipse and lunar eclipse occur when Jupiter and Saturn are in alignment

• A solar eclipse occurs when Earth blocks the light going to the moon. A lunar eclipse occurs when the moon blocks the light coming from the sun.

• A lunar eclipse occurs when Earth blocks the light going to the moon. A solar eclipse occurs when the moon blocks the light coming from the sun.

• A solar eclipse and lunar eclipse occur when Halley's comet passes by Earth

Multiple Choice

Lunar eclipses do not occur every month because the moon, Earth, and sun have to be lined up a certain way.

• True

• False
