Unit 1 Summative S6E5a/S6E5f/ S6E5g (Make- Up Test)

As you leave the Earth’s core and travel towards the crust, what happens to temperature and density?

• Temperature increases: Density stays the same

• Density decreases, Temperature decreases

• Temperature increases; Density decreases

• Temperature increases; Density increases

Using the diagram of Earth’s layers below, which letter in the diagram identifies the mantle?

• Area A

• Area B

• Area C

• Area D

What is the correct order of Earth's layers beginning with the hottest and most dense layer?

• outer core, mantle, inner core, and crust

• inner core, outer core, mantle, and crust

• crust, mantle, outer core, and inner core

• mantle, inner core, outer core, and crust

Using the diagram of Earth’s layers below, which letter in the diagram identifies the layer scientists believe to be in a liquid state?

• Area A

• Area B

• Area C

• Area D

Looking at the 4 layers of the Earth interior, which layer would be the most dense and why?

• The inner core because of pressure

• The mantle because of pressure

• The outer core because of composition

• The mantle because of composition

What causes convection currents to move within the mantle?

• Heat from the core causes material to become less dense and rise towards the surface and sinks after it reaches surface and cools

• Heat from the sun causes material to become less dense and rise towards the surface

• Heat from the sun causes material to become more dense and rise towards the surface

• Heat from the core causes material to become more dense and rise towards the surface

1. When looking at the shape of the continental shelves that surround South America and Africa, it can be observed that the continental shelves fit together even though they are separated by the ocean. Which of the following best explains these observations?

• Ocean currents have eroded a similar pattern on the two coastlines.

• The continental shelves float on the ocean as it moves them back and forth.

• Land masses that form in similar situations usually have similar shapes.

• Convection currents separated the tectonic plates, separating these continents.
