Earth Science Retest

What causes the seasons on Earth?

• The distance of Earth from the Sun

• The tilt of Earth’s axis as it orbits the Sun

• Changes in the Sun’s energy output

• The Moon’s gravitational pull

Which movement of Earth causes day and night?

• Revolution around the Sun

• Rotation on its axis

• Tilt of the axis

• Gravity from the Moon

How long does it take for Earth to complete one revolution around the Sun?

• 24 hours

• 30 days

• 365.25 days

• 12 hours

During which moon phases do spring tides occur?

• First and third quarter

• Full and new moon

• Waxing crescent and waning gibbous

• Only during a solar eclipse

Neap tides happen when the gravitational forces of the Sun and Moon are

• Working together to create higher tides

• Weakening Earth's gravity

• Pulling in opposite directions, making tides lower

• Making ocean water evaporate faster

The four main layers of Earth, from the outermost to the innermost, are:

• Crust, Mantle, Outer Core, Inner Core

• Mantle, Crust, Inner Core, Outer Core

• Inner Core, Outer Core, Mantle, Crust

• Outer Core, Inner Core, Mantle, Crust

The four main Earth spheres are:

• Atmosphere, Hydrosphere, Lithosphere, and Biosphere

• Atmosphere, Hydrosphere, Lithosphere, and Asthenosphere

• Atmosphere, Hydrosphere, Lithosphere, and Cryosphere

• Atmosphere, Hydrosphere, Lithosphere, and Magnetosphere

Different parts of Earth experience different amounts of sunlight during the year because:

• the Earth is flat.

• the Earth rotates on its axis.

• the Earth is tilted on its axis.

• the Earth is stationary.

Explain why we have high and low tides, and how the Moon influences them.

• The gravitational pull of the Moon causes the water to bulge out on the side closest to the Moon, creating high tide, while the opposite side also experiences a high tide due to inertia.

• The Moon's light reflects on the water, causing it to rise and fall, creating high and low tides.

• The Moon's phases determine the height of the tides, with full moons causing the highest tides.

• The Moon's orbit around the Earth causes the tides to change direction, leading to high and low tides.

Earth’s revolution and axial tilt work together to create:

• day and night

• summer and winter

• high and low tides

• eclipses
