In the Beginning Lesson Set 1 Mastery Check-H

Unravel the universe! Master Big Bang theory, galaxies, gravity, and our cosmic address.

Which of the following sets of space objects are in order from largest to smallest: a solar system, moon, the universe, a galaxy, star, planet Moon, planet, star, galaxy, the universe, solar system the universe, galaxy, solar system, moon, planet, star the universe, galaxy, solar system, star, planet, moon What is the approximate age of our universe? 1 billion years 140 billion years 14 billion years 14 million years What is outside of the universe? black holes galaxies nothing aliens What is a galaxy, and what type is our galaxy? large system of stars held together by gravity; irregular galaxy large system of stars held together by gravity; elliptical galaxy small system of stars held together by gravity; irregular galaxy large system of stars held together by gravity; barred spiral galaxy Where our we located in the galaxy? middle of it; Andromeda arm small arm; Orion arm middle of it; Orion arm small arm; Andromeda arm Match the term with the correct definition. telescope a device used for looking at objects that are too far away to see well with the naked eye orbit the path of one object as it revolves another revolve one object moves around another object astronomer a scientist who studies the universe and objects in it Select the major pieces of appropriate evidence scientists have found for the Big Bang Theory. Hubble telescope found red shifting light of galaxies which means they are moving away COBE satellite explored more the cosmic background radiation Composition of Stars shows they are mostly made of hydrogen and helium The universe began with a cluster of stars appearing periodically Which statement correctly describes the theory of the Big Bang? all matter and energy once expanded out of a single point little explosions happened all over the universe, creating matter and energy all matter and energy once exploded from many points the universe is an unchanging steady state Our Cosmic Address Create the correct sequence for our Cosmic Address 1st Planet Earth 2nd Solar System 3rd Milky Way Galaxy 4th Local Group 5th Virgo Supercluster 6th Observable Universe What happens to gravity as you get further in the distance? increases decreases nothing stays the same The amount of force you feel from the gravity of an object depends on three things. Which of these is not one of those three things? How far away you are from that object. How much you weigh. How much mass the object has. How much mass you have. What is the shape of our orbit, and which scientist discovered it? elliptical; Johannes Kepler circular; Galileo Galilei circular; Johannes Kepler elliptical; Galileo Galilei
