100
German scientist famous for developing the theory of continental drift?
What is Alfred Wegener?
100
Which plate boundary creates the most friction?
What is fracture?
100
The process by which soil and sediments are moved from one location to another (think of the river model)...
What is erosion?
200
The innermost solid layer of Earth.
What is the inner core?
200
The upper mantle and the crust combine to form the...
What is lithosphere?
200
Scientists believe Earth's continents were once joined together as a giant land mass.
What is Pangaea?
200
At a colliding continent to continent boundary, this land-form can be created. At an oceanic to continental boundary, this land-form can be created.
What is C-C mountains and C-O trench and volcanoes?
200
When sediments are dropped in new place it is called .................... When this occurs at the mouth of a river where it flows into a larger body of water, it is called a...................
What is deposition and river delta?
300
The layer of Earth below the crust that contains most of Earth's mass.
What is mantle?
300
Scientists believe this causes the earth's magnetic field.
What is the rotation of the solid inner core inside the liquid outer core?
300
3 types of scientific evidence support continental drift.
What is the continents fit together like PUZZLE pieces, rock formations, and fossils?
300
At a spreading boundary of two oceanic plates, a land-form is created. At a spreading boundary of two continental plates, a land-form is created.
What is O-O mid-ocean ridge (underwater mountains) and C-C rift valley (like Iceland)?
300
What are the four main causes of erosion and name one land-form each creates.
What is water (canyons, beaches, and river deltas) ice (mountains, valleys, and lakes), gravity (mud slides and land slides), and wind (sand dunes, soil erosion (Dust Bowl)?
400
The layer of earth that is both solid and liquid.
What is the mantle?
400
In convection, warm liquid or gases ..................and cold liquid or gases......................
What is RISE and FALL?
400
A scientist who studies Earth's structure, composition, and history.
What is a geologist?
400
At a fracture boundary what land-form is created?
What is earthquakes?
400
What do engineers design to prevent beach erosion?
What is jetties and sea walls?
500
The liquid layer of earth composed primarily of molten iron and nickel.
What is the outer core?
500
Process in the mantle do scientists believe cause tectonic plate movement.
What is convection currents?
500
Some scientist believe that because of convection in the mantle and movement of the lithospheric plates, this phenomenon will happen again.
What is pangea?
500
The Pacific plate is often called.....................because along its plate boundaries it has a lot of ....................and .............................
What is The Ring of Fire, Volcanoes, and Earthquakes.
