Which statement about Earth's galaxy is correct?

• Earth belongs in the Milky Way Galaxy which is spiral shaped.

• Earth belongs in the Black Eye Galaxy which is elliptical shaped.

• Earth belongs in the Pinwheel Galaxy which is spiral shaped.

• Earth belongs in the Andromeda Galaxy which is elliptical shaped.

Which description best defines a galaxy?

• patterns in space formed by constellations

• collections of stars and their solar systems, dust, and gases

• all of the matter and energy that is in space

• a black hole that is found at the center of all solar systems

A scientific article about the universe will MOST likely describe the universe as

• consisting of billions of galaxies.

• being less than two billion years old.

• containing approximately ten planets

• becoming smaller over time.

What was the Big Bang?

• model states that the universe began with expansion occurring in all areas of the universe. Over time, the expansion slowed and the matter in the universe contracted. Then the process began again, repeating over and over.

• The universe always has been the same as it is now, that it has always existed and always will, and as matter in the universe expands outwards, new matter is created to keep the overall density the same

• theory of the universe that states that all matter and energy was once packed in a tiny, dense singularity that then exploded about 14 billion years ago. The universe then began expanding and cooling, and is still doing so today.

Which theory or theories are accepted today?

• Geocentric

• Heliocentric

• Steady State Model

• Oscillating Model

• Big Bang Theory

What is the difference between a Heliocentric & Geocentric model of the universe?

• There is no difference.

• One has the sun in the center and one has the earth at the center.

• One is a galaxy and one is a solar system.

What tool did Galileo use to make his discoveries?

• Satellite

• Telescope

• Space Shuttle
