Unit 3 Lessons 1-5 Review

What is a reason people need certain substances beyond Earth?

• To create new chemical reactions

• To support the kinds of work they might want to do

• To increase the speed of space travel

• To reduce the cost of living

Why must most substances needed for space travel be found, recycled, or made on-site?

• Due to the lack of resources on Earth

• Because of the scale of the solar system and cost of space travel

• To improve the quality of life in space

• To enhance the speed of chemical reactions

Why is water better at eroding sediment than other liquids?

• Because it is a nonpolar molecule

• Because it is a polar molecule

• Because it has a high boiling point

• Because it is a solid at room temperature

What allows polar molecules to erode materials more easily than nonpolar molecules?

• Their ability to absorb light

• Their ability to separate ions and break down solids

• Their high density

• Their low melting point

What causes polar regions on molecules?

• A greater amount of negative or positive charge

• A higher temperature

• A lower density

• A smaller molecular size
