Earth And Space Science Semester 2 Final

The 'Earth and Space Science Semester 2 Final' assesses knowledge on universe expansion, desalination, star life cycles, groundwater terminology, Earth's orbit, and climate stability. It's designed to evaluate understanding in...

Questions: 51 | Attempts: 125 | Last updated: Jan 18, 2024

Sample Question 1
It is estimated that the big bang occurred 14 billion years ago. Most likely, what will the universe will be like 14 billion years from now?

The universe is still expanding, so in 14 billion years it will be even more spread out.

Many stars will become black holes, and the universe will collapse back into itself.

The universe will have expanded to the point of becoming empty and will no longer exist.

Relative distances between galaxies will become shorter as universal expansion slows.

Sample Question 2
Desalination is one way to increase Earth’s supply of fresh water. Based on what you’ve read, how would you define desalination? Why is it not in wider use around the world?

It introduces chemicals into the water.

It remains too costly.

It doesn't always work.

It disrupts ocean environments.

Sample Question 3
Stars are balls of gas that give off an enormous amount of electromagnetic energy due to the nuclear _____ taking place within them.

Fission

Emissions

Alignment

Fusion
