Earth Spheres
Living sphere
What is the biosphere?
Heat and pressure creates these rocks
What is metamorphic?
Outer most layer of the earth
What is the crust?
Plate boundary that creates mountains.
What are convergent boundaries?
This fossil was found on South America and Africa, making Wegener think those two continents were once joined together
What is the mesosaurus?
When people breathe we interact with this sphere
What is the atmosphere?
Rocks that contain fossils.
What is sedimentary rocks?
Layer of the Earth that is like a metal ball of iron or nickel
What is inner core?
Rocks found further from the mid-ocean ridge compared to rocks near the ocean ridge
What is older?
What is the continental drift theory?
Glaciers and ice are part of this sphere.
What is the hydrosphere?
When rocks are eroded they become this.
What are sediments?
What is the mantle?
Plate boundaries that create faults
What are transform boundaries?
A chain of underwater mountains along which sea-floor spreading occurs
What is a mid-ocean ridge?
This process takes water in the hydrosphere and turns it into vapor, becoming part of the atmosphere.
What is evaporation?
As lava cools quickly this rock is formed (be specific)
What is extrusive igneous rocks?
This crust sinks back into the mantle, recycling over and over
What is the oceanic crust?
As two oceanic plates collide these deep parts of the ocean are created
What are trenches?
Mushrooms are part of this sphere
What is the biosphere?
Minerals are formed when magma cools underground and through this process
What is water evaporation?
What is density?
This plate subducts under, melts, and creates a volcano
What is an oceanic plate?
Jigsaw, fossils, mountain ranges, and this were pieces of evidence to support Wegeners Theory of Continental Drift
What are ancient climates?
