Two Ocean plates converging

Two Continental plates converging

Diverging plates

Transform Fault Boundary

A land bridge once existed between Africa and S. America

The Atlantic Ocean was once much more shallow

Migration between Africa and S. America was once possible

The Earth was once much smaller in size

The continental plate isn't hot enough to cause volcanoes

Volcanoes are not associated with convergent plate boundaries

Rising magma from melted plates can't break through continental crust

Volcanoes only occur on islands in the ocean and not on land

the magnetic field of the earth

heat from the sun

gravity between the earth and moon

ocean currents

An orange, it has a thin peel with a solid, but watery inside

A bowling ball, it is completely solid all the way through

An egg, it is solid at the core, surrounded by liquid and then a hard outer shell

A geode, it is hollow at the center with a strong, hard, outside layer

inner core, outer core, crust, mantle

inner core, mantle, outer core, crust

crust, inner core, outer core, mantle

mantle, inner core, crust, outer core

The inner core is liquid and the outer core is solid

The inner core is made from magma and the outer core is metal

The inner core is cool and the outer core is hot

The inner core is hot and the outer core is cool

The mantle surrounds the outer core

It is composed of iron- and magnesium-rich rocks

The density of the rocks is higher than water

The density of the rocks is lower than the outer core

They have drilled holes into the Earth and sent sensors down to its center

They study very large canyons that have been uplifted from the center of the Earth

They study the movement of water waves in the ocean

They have built a ship that can dig into the Earth and take a team of scientists to its center

It is in the middle of the ocean

It is a divergent boundary where tectonic plates move apart

It is a place where new lithosphere is created

It is a site of deep see volcanoes and mountains

It causes earthquakes

It causes volcanic eruptions

It provides a mechanism for Plate Tectonics

It explains times of rapid change on the Earth's surface
