Origins of the Universe Guided Lesson

Multiple Choice

• Hydrogen and Oxygen

Multiple Choice

What force initially caused stars and then galaxies to form?

• Aurora Borealis

• Convection Currents in Nebulas

• Gravity

• Electromagnetic Radiation

Multiple Choice

• increased

• stayed the same

Multiple Choice

An astronomer that studies the universe's origin.

• Astronaut

• Astrologist

• Cosmotologist

• Cosmologist

• Astronomer

Multiple Choice

Cosmologists used data from spectral reading that showed light from distant galaxies was "red shifted". What did this lead them to conclude?

• Distant galaxies are moving towards us and will soon meet

• Distant galaxies are moving randomly

• Distant galaxies are moving away from us and must have been joined at a single point in the past

• Distant galaxies are spooky and should be feared

​Some text here about the topic of discussion.

Multiple Choice

Which statement is true about the movements of the universe?

• Most galaxies are moving toward us.

• Most galaxies are moving away from us.

• Both of these stars are moving towards us.
• Both of these stars are blueshifted.
• The star Sirius is closer to us.

Multiple Choice

What is the Doppler Effect?

• A change in frequency due to the movement of an object towards or away from Earth

• When a wave overlaps with another wave

• When a wave bounces off of another object

• When a wave bends due to traveling through a different medium

Multiple Choice

Galaxies that are REDSHIFTED are:
