Sun, Earth and Moon System Review

Explore the Sun, Earth, and Moon system! Learn about orbits, seasons, tides, and eclipses.

Earth's Rotation and Revolution Watch the video and answer the questions that follow. How long does it take for the Earth to complete one REVOLUTION around the sun? 1 day 24 hours 11 months 365 days As the Earth rotates on its axis, it creates the seasons day and night the hemispheres eclipses The tilt of the Earth's axis causes the North and Southern Hemisphere to vary in exposure to the sun. This creates seasons eclipses day and night rotation of the Earth What looks to us like the sun is moving in the sky, is really caused by the motion of the Earth around the sun. true false When the part of the Earth you live in leans AWAY from the sun... days are shorter and it is summer days are longer and it is summer days and shorter and its winter days are shorter and it is winter Seasons and the Sun Take a look at the summary of what causes our 4 visible seasons. Be prepared to answer questions after the video. How are the sun and seasons linked? the rotation of the sun around the Earth the angle of sun's light on the earth the tilt of the sun's axis the speed of the Earth's rotation around the sun Why are temperatures in the spring and fall moderate? the Earth is tilted towards the sun the Earth is tilted away from the sun the Earth isn't tilted toward or away from the sun there is no tilt of the Earth during those seasons In looking at this graph, when are temperatures the greatest in Toronto, Canada? winter months spring months summer months fall months Based on what you have learned, why are temperatures higher during those months in the graph above? the Earth is tilted towards the sun the Earth is tilted away from the sun the Earth's tilt creates equal distribution of sunlight those months because the sun's surface increases during those months Which of the following is NOT a characteristic of summer? days are longer temperatures are hotter less direct sunlight nights are shorter ORBITS Why They Happen So, why doesn't the moon just crash into the Earth? And why doesn't the Earth crash into the Sun? What are orbits exactly and why do they happen? Well, it has to do with gravity and velocity. In this episode of Crash Course Kids, Sabrina talks to us about how these things work and why we don't. Which of the following ORBITS around the Earth? the planets the sun the moon all of the above How long does it take the moon to orbit the Earth? 27 days 27 months 30 days one year What do artificial satellites do for us? monitor drought forecast weather communicate with our phones and other devices all of the above Which of the following is a false statement about the International Space Station (ISS)? It is the largest artificial satellite orbiting the Earth It was created as a result of efforts between many countries It is a spy station that Russia uses to watch the USA People actually live on the ISS and research How does the moon stay in space? the balance of the gravitational pull and speed of orbit the balance of the gravitation pull and the sun's brightness the balance of the speed of movement and size of the moon the balance of the gravitational pull and size of the moon WHAT CAUSES THE TIDES OF THE OCEAN??? Which of the following causes the tides of the ocean? the gravitational force of the moon the gravitational force of the Earth the rotation of the moon all impact the tides of the ocean Which of the following orbits around the Earth? the moon the sun the planets all of the above When the sun, the Earth and the moon are in a straight line, we get our highest tides, called _ tides. neap tides summer tides spring tides low tides Fill in the blanks below based on the video that you just viewed. Tides are highest during the new and full moons because the sun, moon, and Earth are in a straight line. These tides are called spring tides. When the sun and moon are at right angles to one another, we get our lowest tides called neap tides. Solar Eclipse 101 Review solar eclipses by watching the video and answering the questions. What occurs when the moon passes between the Earth and the sun and casts a shadow on the Earth? solar eclipse lunar eclipse lunar phases change in seasons All solar eclipses completely cover the view of the sun seen from the Earth. true false Why are eclipses predictable? the moon stays in one place because the moon is larger than the sun the orbit of the Earth and Moon are continuous Moon Phases - BrainPOP UK Watch the summary of moon phases and answer the questions. Fill in the blanks. The moon orbits around the Earth as the Earth orbits around the sun. Why don't we get a solar and lunar eclipse each month when the sun, moon and Earth are in perfect alignment? because the intensity of the sun changes throughout the month. because they align on the other side of the world and we just don't see it because the orbit of the moon changes in speed and location. because the moon's orbit is tilted 5 degrees. Moon Phases Lable the phases of the moon in the diagram below. New Moon Waning Crescent Last Quarter Waning Gibbous Full Moon Waxing Gibbous First Quarter Waxing Crescent
