Earth Science Quiz

Put the layers of the earth in order from HOTTEST to COLDEST:

• inner core

• mantle

• outer core

• crust

What name is given to the type of crust that is primarily made up of basalt and is found at the bottom of the oceans?

• Divergent Crust

• Lithospheric Crust

• Oceanic Crust

• Continental Crust

We journeyed to the center of the Earth, and when we got there we discovered that the core has two parts. One part is liquid and is called the _____________. The other part is dense and solid and is called ____________.

​ ​

• outer core, inner core

• inner core, outer core

• mesosphere, asthenosphere

• asthenosphere, mesosphere

What is created at the mid-ocean ridge during seafloor spreading?

• Old oceanic crust

• New continental drift

• Old contiental crust

• New oceanic crust

What happens when a continental plate and an oceanic plate collide at a convergent plate boundary?

• Non-volcanic mountain ridges form.

• the less-dense continental plate subducts under the mores-dense oceanic plate, forming volcanoes.

• the more-dense oceanic plate subducts under the less dense continental plate, forming volcanoes.

• they collide because the have the same density.

What can happen when two continents collide?

• mountains form

• a mid-ocean ridge forms

• a divergent boundary forms

• a subduction zone forms

Pieces of the same mountain chain are now separated on two different continents by an ocean today. What conclusion can you make that would be true about this?

• the mountains formed after Pangaea separated

• the mountains were once one during Pangaea

• the mountains are still forming due to collisions of continental crust

• there isn't enough info to answer

Most scientists rejected Alfred Wegener's idea of continental drift because

• they were afraid of a new idea

• Wegener was interested in what Earth was like millions of years ago.

• Wegener used several different types of evidence to support his idea

• Wegener could not identify a force strong enough to move the continents

What conclusion can be drawn from the Theory of Plate Tectonics, Pangaea, and seafloor spreading?

• Earth is losing heat

• Earth's geography changes

• Earth is expanding

• Earth is shrinking

Which of the following is NOT evidence that Alfred Wegener used to support his theory?

• similar landforms on different continents separated by oceans

• shapes of continents fit together like a puzzle

• identical fossils found on continents separated by oceans

• continents continues to move each year
