Which space mission put the first man on the moon? Mercury missions Voyager missions Apollo missions Space missions I am an object in the solar system with an orbit that may take thousands of years to complete. I am composed mostly of ice and my tail glows when I'm around the sun. I am a/an: Sun Meteor Asteroid Comet I am made of a piece matter (rock) from outer space. I begin to burn up when I fall through Earth's atmosphere. I am referred to as a "shooting star". Sun Meteor Asteroid Comet I am composed of rock and/or metal, I orbit the sun between Mars and Jupiter. I am a/an: Sun Meteor Asteroid Comet The sun is at the center of our solar system and creates a huge amount of force (gravity) which holds all the planets and other objects in orbit. What would happen if the sun lost its gravity?
The planets would blow up Everything would slow down and stop moving Planets would travel away from the sun in a straight line. Everything would continue as it always has I am a round object that orbits the sun. I can be made of solids (like rock), or gases. I may or may not have other smaller objects orbiting me. I am a/an: Planet Meteor Comet Asteroid The orbital path of the planets in our solar system can be described as: Circular Elliptical irregular Rectangular Gravity exists between all objects that have mass.
True False Why does it take Neptune nearly 165 years to revolve around the sun and Earth's revolution is only 365 days? (think about it......) Neptune rotates fast, so therefore it revolves around the sun slowly. None of the above Neptune is a gas giant and Earth is a terrestrial planet Neptune is much farther away from the sun and has a much larger orbit. Although Earth is the largest of the inner terrestrial planets, which other planet is similar in size? Mars Mercury Venus Jupiter The spinning (rotation) of a planet, moon, or sun on its axis is called: (look in journal) rotation twirling revolution spinnaker One orbit of an object around another object in space like Earth orbiting the sun is called: any of the above. The terms are interchangeable. revolution orbitation rotation A space probe is used to carry equipment and gather data in places or situations that a crew, or humans cannot go. Which of the following would be the BEST use of a space probe? In the ocean Neptune Mount Everest On a space station As mass increases, what happens to gravitational force? Stays the same Increases Decreases I don't know As the distance between 2 objects increases, what happens to gravitational force? increases stays the same decreases I don't know Mercury, Venus, Earth and Mars are the inner planets. They are also called........ Planets with water Terrestrial planets atmospheric planets Jupiter, Saturn, Uranus, and Neptune are the outer planets. They are also called........ Lunar planets Gas giants Large colorful planets All the terrestrial planets have more than one moon. True False A reusable spacecraft that transports astronauts, satellites, and other materials to and from space.(Looks like an airplane) Space ship Space station Space shuttle Voyager 1 The Curiosity rover was sent to Mars to explore. It is an unmanned probe meaning people are not on board. These missions have many advantages over mannedmissions (with people). What could possibly be a disadvantage of having a robot instead of people to explore? Unmanned missions cannot predict and problem solve unexpected situations Unmanned missions can outlast humans Unmanned missions do not require water and air to function With our current capabilities, it would take over 70,000 years to reach the closest star outside our solar system. What improvements need to be made for future space travel? B. unmanned spacecraft improvement (improved computer technology) A. spacecraft speed improvement (go faster) C. manned spacecraft improvement (better life support) A and B B and C What feature can form at a mid-ocean ridge? volcano tornadoes mountains peninsula |
