Space Summative Review Test: Thursday, February 23rd Inner planets: Mercury, Venus, Earth, Mars Outer planets: Jupiter, Saturn, Uranus, Neptune The closer a planet is to the sun the hotter it is. The farther away a planet is from the sun the colder it is. SUN No atmosphere No liquid water Many craters because it lacks atmosphere Rocky crust Reflect sunlight Smaller than the earth and sun No wind or moving water so surface doesn’t change much Spherical in shape Rotates on its axis No life Satellite of the earth Takes 29.5 days to revolve or orbit around the Earth 3rd planet from the sun 4 times larger than the moon Rotates every 24 hours on an axis Has water and atmosphere Only planet that supports life Sphere of rock Has gravity Rocky crust Reflects sunlight Satellite of the sun Has an atmosphere Few craters Takes 1 year (365 ¼ days) to revolve or orbit the sun Weather, describes the daily conditions in the atmosphere of a local area. It includes conditions such as cloud cover, wind, humidity, precipitation and temperature, which is how hot or cold the air is. Sphere of burning gases Made of hot gases Rotates on an axis Source of heat and light for our solar system Medium sized star A million times bigger than the Earth No real surface Center of our solar system Largest object in our solar system Moon EARTH Weather is constantly changing. Scientists who predict, or forecast, the weather can’t usually make forecasts beyond 10 days. Even weather reports cannot guarantee that the forecasts will be accurate. Weather is over a short period of time and changes often. Climate is the type of weather in an area averaged over a long period of time, such as 30 years or more. Climate is consistent and doesn’t change. The climate of an area describes its average temperatures, precipitation, humidity, wind, cloud cover, and other weather conditions over long periods of time. Climate is what the weather usually is in a certain area. Tides Tides are the daily rise and fall of Earth’s waters on its coastlines. As the tide comes in, the level of water on the beach rises, and as the tide goes out, the level of water on the beach goes down. Tides occur in all bodies of water, but they are most noticeable in the ocean and large lakes. The Moon’s gravity affects the water on Earth’s surface. Since the Moon is close to the Earth, it has a strong gravitational pull on it (closer objects have stronger gravitational pull) which CAUSES THE TIDES Low tide There are 2 high tides and 2 low tides every 24 hours. There is approximately 6 hours between the high tide and low tide. Moon Phases We see the moon from Earth as it orbits us. The way the moon appears changes depending on where the moon is in its orbit. 1 2 3 4 In the lunar cycle, the light starts on the right and gradually grows larger. The appearance of light moves from right to left. Phase Names: 1. new moon 2. Waxing crescent 3. First quarter 4. waxing gibbous 5. Full moon 6. Waning gibbous 7. third quarter 8. Waning crescent
