Who developed the theory of continental drift

Alfred Wegener

What type of Plate boundary forms mountains?

A convergent boundary because two plates are moving toward each other and they usually push up against each other, forming a mountain chain

Why does Oceanic Crust gets subducted underneath Continental Crust?

Basalt is denser than granite

Two types of plate boundaries will we find volcanoes

Convergent and divergent

Which boundary or zone adds new material to the lithosphere (the hard outer crust of the Earth)

Divergent boundary

T/F As you go deeper inside Earth, pressure and temperature decrease

False

T/F cold fluids rise and warm fluids sink

False

Himalayas (Mountains)

Formed by convergent boundaries

African Rift Valley

Formed by divergent boundaries

San Andreas Fault

Formed byTransform boundaries

Example of Conduction

Grabbing a hot mug of coffee

The two magnetic metals present in the core

Iron and Nickel

When a fluid gets hotter, what happens to it's density?

It decreases

Example of convection

Magma in the Mantle

What forms when 2 continental plates collide?

Mountains

What kind of loop system is energy on Earth?

Open

Theory that all of the continents were together about 200 million years ago in a giant landmass

Pangea

Divergent

Plates move apart from each other

Convergent

Plates run into each other

Transform

Plates slide past each other

What would NOT be found near Convergent Plate Boundaries

Rift valleys

What piece of information did Alfred Wegener not have to help prove the Theory of Continental Drift?

Seismic Wave data to prove the Earth is not just a solid

Example of radiation

Sun's energy reaching Earth

In what way does a transform boundary differ from the other boundary types

The plates move in a direction that is parallel to the boundary line.

Order the layers of the Earth (top to bottom)

crust, mantle, outer core, inner core

What type of boundary is at a mid-ocean ridge?

divergent

What happens at transform boundaries?

earthquakes

The crust and upper part of the mantle is called

lithosphere

sinks

An example of a feedback mechanism that helps our body regulate temperature
