Solar System Review
Describe what causes a lunar eclipse AND draw a labeled model of a lunar eclipse.
A lunar eclipse is caused when the Earth passes directly between the sun and the moon.
Describe what causes a solar eclipse AND draw a labeled model of a solar eclipse.
A solar eclipse is caused when the moon passes between the sun and the Earth. The moon casts a shadow on Earth's surface.
How often does Earth rotate?
Earth makes a full rotation every 24 hours
How often does Earth revolve around the sun?
Earth revolves around the sun once in in one year.
What causes Earth's day and night?
Earth's day and night are caused by Earth's rotation. As the sun rotates toward or away from the sun once every 24 hours, day or night occurs.
Identify the force that causes objects dropped on Earth to fall toward Earth's center AND draw arrows showing the direction each person would fall.
Gravity is the force that caused objects dropped on Earth to fall toward Earth's center.
How many times does Earth revolve around the Sun in one year?
It takes 365.25 days -or one year- for the Earth to revolve around the Sun.
Look at the image. If the sun is in this position in the sky, what time is it most likely?
Just remember, the sun rises in the east and sets in the west. In this example, the time is 6:00 am, 12:00 pm, and 6:00 pm
List the names of the planets in our solar system in order from the Sun.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune My very educated mother just served us nachos.
Describe what causes moonlight
Moonlight is caused mostly be the sun's light reflecting off the surface of the moon then striking Earth.
Explain what causes ocean tides on Earth AND identify the number of low and high tides each day.
Ocean tides on Earth are caused by the pull of gravity. There are 2 high tides and low tides each day.
What season has the longest daylight? How do you know?
Summer has the longest daylight because the sun is higher in the sky which gives more hours of daylight and the Northern Hemisphere receives more direct sunlight.
How many times does Earth rotate in one year?
The Earth rotates 365.25 times in one year.
Identify the direction that the Earth rotates AND draw a model.
The Earth rotates on its axis from west to east.
What force (and from where) causes the Moon to stay in the Moon's orbit?
The Earth's gravity causes the Moon to stay in the Moon's orbit.
What force (and from where) causes Earth to stay in Earth's orbit?
The Sun's gravity causes Earth to stay in Earth's orbit.
Explain why the length and direction of shadows changes over a day from sunrise, noon, and sunset.
The angle of the Sun, low in the sky to higher in the sky, changes the length of the shadow cast behind an object.
Explain why a person can jump higher on the moon than on Earth?
The gravitational pull is stronger on Earth than on the moon.
How often does the moon revolve around the Earth?
The moon revolves around the Earth once a month; about 28 days.
Explain why the moons, planets, the Sun and stars tend to be spherical in shape.
The moons, planets, the Sun and starts tend to be spherical in shape because of the constant pull of gravity toward the center of these very large objects.
If two pictures were taken of the same image at the same time in summer and winter, which would have the longer shadow?
The path of the sun is lower in the sky in winter which makes a shadow longer.
Explain what causes people on Earth to see the phases of the moon.
The reason we see different phases of the Moon here on Earth is that we only see the parts of the Moon that are being lit up by the Sun.
Explain what causes the seasons on Earth?
The seasons on Earth are caused by the Earth being tilted on its axis. This means the Earth's surface is being unevenly heated by the sun. The Earth's 23.5-degree tilt causes different parts of the Earth to receive direct or indirect sunlight. This causes seasonal changes in the Northern Hemisphere compared to the Southern Hemisphere.
Is the sun a star?
The sun is a star because it is the closest star to Earth which is why you can see it in the daytime.
Explain why the Sun, which is a star, appears larger and brighter than other stars.
The sun is so much brighter than other stars because it is the closest star to Earth. Only 93,000,000 miles away from Earth.
If the Earth were to spin around on its axis twice as fast as it does right now, what would happen?
We would have 12 hour days and 12 hours nights. At the equator, we would have 6 hours of day and 6 hours of night.
What causes the sun, or the stars, to appear to move across the sky?
When the Earth rotates on its axis, it moves west to east. This rotation makes the sun looks like it rises in the east, moving across the sky, and sets in the west. The sun isn't moving. The earth is rotating.
What season is it when the sun in different paths in the sky?
When the sun is high in the sky, it is summer. When the sun is in the middle of the sky is spring and fall. When the sun is low in the sky and it's winter.
Explain what causes most waves in the ocean.
Wind causes most waves in the ocean. The wind blows across the surface of the ocean and caused friction with the water surface and the wind causes the water surface to move.
In addition to the 8 planets and the Sun, identify at least 5 other major objects in our solar system.
meteors, asteroids, moon, comets, dwarf planets
Phases of the moon in order
new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent
phases of the moon
the progression of changes in the moon's appearance during the month
Spring tides occur when
the sun, moon, and earth are in a line
Neap tides occur when
the sun, moon, and earth form right angle
