Living sphere

What is the biosphere?

100

Heat and pressure creates these rocks


What is metamorphic?

100

Outer most layer of the earth

What is the crust?

100

Plate boundary that creates mountains.

What are convergent boundaries?

100

This fossil was found on South America and Africa, making Wegener think those two continents were once joined together

What is the mesosaurus? 

200

When people breathe we interact with this sphere

What is the atmosphere?

200

Rocks that contain fossils.

What is sedimentary rocks?

200

Layer of the Earth that is like a metal ball of iron or nickel

What is inner core?

200

Rocks found further from the mid-ocean ridge compared to rocks near the ocean ridge

What is older?

200
Idea that suggested the Earth's continents were once joined in a supercontinent, later breaking apart to where they are today.

What is the continental drift theory?

300

Glaciers and ice are part of this sphere.

What is the hydrosphere?

300

When rocks are eroded they become this.

What are sediments?

300
Convection currents are found in this layer of the Earth

What is the mantle?

300

Plate boundaries that create faults

What are transform boundaries?

300

A chain of underwater mountains along which sea-floor spreading occurs

What is a mid-ocean ridge?

400

This process takes water in the hydrosphere and turns it into vapor, becoming part of the atmosphere.

What is evaporation?

400

As lava cools quickly this rock is formed (be specific)

What is extrusive igneous rocks?

400

This crust sinks back into the mantle, recycling over and over

What is the oceanic crust?

400

As two oceanic plates collide these deep parts of the ocean are created

What are trenches?

400
Evidence Wegener was lacking in his theory of continental drift
The how/sea floor spreading
500

Mushrooms are part of this sphere

What is the biosphere?

500

Minerals are formed when magma cools underground and through this process

What is water evaporation?

500
Temperature and this increase as you go deeper into Earth's layers

What is density?

500

This plate subducts under, melts, and creates a volcano

What is an oceanic plate?

500

Jigsaw, fossils, mountain ranges, and this were pieces of evidence to support Wegeners Theory of Continental Drift

What are ancient climates?
