QuestionAnswer
Describe the physical properties, locations, and movements of the SUN Physical Properties: Made of Helium, Hydrogen, medium sized star Location: Center of Solar System Movements: Stationary
Describe the physical properties, locations, and movements of the INNER PLANETS Physical Properties: Rocky Surface and small Location: First 4 closest to the Sun Movements: orbit the sun
Describe the physical properties, locations, and movements of the OUTER PLANETS Physical Properties: Gas Location: Last 4 from to the Sun Movements: orbit the sun
Describe the physical properties, locations, and movements of the MOONS Physical Properties: Small and vary in composition; natural satellite Location: Around the planets; multiple moons Movements: orbit the planets
Describe the physical properties, locations, and movements of the METEORS Physical Properties: Rock smaller than 300 feet Location: Earth's Atmosphere Movements: moves toward Earth
Describe the physical properties, locations, and movements of the ASTEROIDS Physical Properties: a piece of rock more than 300 feet Location: Asteroid Belt Movements: Orbit Sun between Mars and Jupiter
Describe the physical properties, locations, and movements of the COMETS Physical Properties: frozen lump of ice, gas, and rock Location: across solar system Movements: Orbit the sun
Describe the physical properties, locations, and movements of the KUIPER BELT Physical Properties: Ice Location: beyond Neptune Movements: Orbits/revolves around sun
Describe the physical properties, locations, and movements of the OORT CLOUD Physical Properties: Ice Location: Surrounds our Solar System Movements: Moves doesn't orbit
Name the inner planets. Mercury, Venus, Earth, and Mars
Name the outer planets. Jupiter, Saturn, Uranus, and Neptune
What two factors keep the planets in orbit around the sun? Gravity and Inertia
If mass increases between two objects, then the gravitational force will INCREASE or DECREASE? Increase
If the distance between two objects increases, then the gravitational force will INCREASE or DECREASE? Decrease
What two factors affect the gravitational force of objects in space? distance and mass
If there were no longer a gravitation force between Earth and the moon, what would happen to the moon's orbit? Follow Newton's 1st Law and keep going straight out to space.
Which object in our solar system has the strongest gravitational pull and why? Sun-most mass of everything in the solar system
Looking at an image of sun-earth-moon orbit image. It shows the Earth's orbit around the sun and the Moon's orbit around the Earth. Describe the gravitational pull between these celestial objects (objects in space) Earth revolves around the sun because of the Sun's gravitational pull; Moon revolves around the Earth because of gravitational pull.
Name the 5 main reasons life can exist on Earth. 1. length of sun 2. presence of water in all phases 3. moderate temp 4. distance temp to sun 5. atmosphere
Explain the habitable zone in reference to life in a solar system. A distance from a star where the temp is just right.
The diagram shows the future habitable zone of our solar system if the sun expanded. Explain why the Earth will no longer be in the habitable zone. Earth was too close to the sun.
Earth's atmosphere contains ___% oxygen. 21%
Earth's surface is approximately ___% water. 70%
Our atmosphere protects the Earth from collisions with ____ and also protects from the sun's _____. meteors; radiation
Earth's atmosphere helps to maintain moderate ___. (not too cold or too hot) and allows for plants and animals to exchange gases with elements like _____ and ____. temperature; oxygen; carbon
