Unit 8: Astronomy

What is the Big Bang Theory?

• A theory created by scientists that show how the universe was formed

• A theory that explains how the Solar System began

• A powerful explosion of a star

• A system of the Sun and 8 planets rotating around it

What does the Nebular Theory explain?

• How the Solar System began

• How the universe was formed

• The process of which a star changes over time

• The rotation around Earth's own axis

What is the Solar System?

• A system of the Sun and 8 planets rotating around it

• A huge collection of stars, gas, and dust combined together

• Consists of everything that exists in space

• An imaginary line that goes through the center of Earth

What is a Galaxy?

• A huge collection of stars, gas, and dust combined together

• A powerful explosion of a star

• The process of which a star changes over time

• An event in which the Earth's sub polar point passes through the Equator

What does the Universe consist of?

• Everything that exists in space

• A system of the Sun and 8 planets rotating around it

• A huge collection of stars, gas, and dust combined together

• The point at which the Sun reaches the highest and lowest point in the sky

What is Stellar Evolution?

• The process of which a star changes over time

• A powerful explosion of a star

• An object's spinning motion about its axis

• The rotation around Earth's own axis

What is a Supernova?

• A powerful explosion of a star

• A huge collection of stars, gas, and dust combined together

• The process of which a star changes over time

• An event in which the Earth's sub polar point passes through the Equator

What is an Axis in reference to Earth?

• An imaginary line that goes through the center of Earth and divides Earth into two equal halves

• The imaginary line around Earth equally distant from both poles

• A line that is 26 degrees north of the equator

• A line that is 26 degrees south of the equator

What is the Equator?

• The imaginary line around Earth equally distant from both poles

• An imaginary line that goes through the center of Earth and divides Earth into two equal halves

• A line that is 26 degrees north of the equator

• A line that is 26 degrees south of the equator

What is the Tropic of Cancer?

• A line that is 26 degrees north of the equator

• A line that is 26 degrees south of the equator

• The imaginary line around Earth equally distant from both poles

• An imaginary line that goes through the center of Earth and divides Earth into two equal halves
