What is the most outer layer of the Earth?

The most outer layer of the Earth is the crust.

100

Which is lighter: oceanic or continental crust?

Continental

100

How are volcanoes formed?

Volcanoes form when magma from Earth's mantle makes it to the surface.

100

What does SCUBA stand for?

Self-contained underwater breathing apparatus.

100

What type of eye protection should you wear when in the lab?

Goggles

200

What are the different layers of the Earth?

The different parts are the crust, mantle, outer core, and inner core.

200

What happens at a convergent plate boundary?

Two tectonic plates converge/collide with each other.

200

What are the different stages of a volcano?

The three main categories are dormant, active, and extinct.

200

What problems can occur while SCUBA diving?

You can get decompression sickness, also known as, the bends.

200

Why shouldn't you horse-play in the labs?

You could potentially hurt others, you could damage and break lab equipment.

300

How many layers are there on the Earth?

There are 4.

300

What happens at a divergent plate boundary?

Two plates diverge/move apart from each other.

300
How many active volcanoes are there?

There are more than 1500 active volcanoes on the Earth.

300

How can you avoid problems while SCUBA diving?

Eat well, exercise, get rest, and avoid harmful and stressful habits.

300

How should you put out a fire in the lab?

You should use a fire extinguisher.

400

What materials make up the inner core?

The inner core is primarily made up of iron and nickel.

400

What happens at a transform plate boundary?

Two plates will slide past each other.

400

What is the difference between magma and lava?

Magma is liquid rock inside a volcano, lava is liquid rock that flows out a volcano.

400

Can you encounter temperature problems while diving?

You can encounter hypothermia and overheating.
400

What should you do if there is a discrepancy in your experiment?

You should contact an instructor immediately?

500

How deep is the Earth's crust?

The Earth's crust ranges from 5 to 60 kilometers.

500

What kind of geological feature will form in the effect of a convergent boundary?

Strong Earthquakes, volcanoes, and mid-atlantic ridges.

500

Why does it take so long for volcanoes to cool down?

Lava cools slowly because lava is a poor conductor of heat.

500

How can you avoid breathing problems while diving?

Never hold your breath while ascending.

500

Can you wear any type of shoe in the lab?

NO, you have to wear some type of protective footware.
