Plate Tectonics
What is the name of the giant land mass that existed millions of years ago and contained all of the Earth’s continents?
Pangea
What do we call a place where two plates meet?
A boundary
What is the study of rocks and landforms called?
Geology
What do we call little pieces of rocks?
Sediment
What is liquid rock underground called?
magma
The Earth’s crust is broken up into pieces. What do we call these pieces?
Plates
What do we call a place where two boundaries separate or break in the Earth's crust?
Fault Lines
What type of rock comes from magma that cools and hardens?
Igneous
What do we call it when pieces of sediment are deposited below the water?
Deposition
What is liquid rock ABOVE GROUND (surface) called?
Lava
How fast do plates move?
A few centimeters every year
What do we call a boundary where two plates MOVE APART IN TWO PIECES?
What type of rock is made of pieces of other rocks?
Sedimetary
What do we call it when rock is broken up into little bits and pieces by rain, wind and heat?
Weathering
What is an opening in the Earth's crust called?
A volcano
How many BIG tectonic plates are there on Earth?
Seven
What do we call a boundary that MOVES TOGETHER/COMES TOGETHER?
Convergent
What type of rock is made when other rocks are changed by the pressure and heat of the Earth?
Metamorphic rock
What is weathering caused by? (Name at least two).
Rain, wind, sun/heat.
Name two types of volcanoes
OR
Where are most volcanoes found?
shield, cinder, cone.
OR
The Ring of Fire (The Pacific Ring)
Name three events or landforms that can happen/get made because of plate boundary types.
Mountains
Volcanoes
Seafloor
Valleys
Earthquakes
Name a boundary that SLIDES PAST ONE ANOTHER and ONE THING it CAUSES.
Transform -- Earthquakes
How do rocks change back into magma? What rock means "made from fire"?
1.) Melting --- 2.) Igneous
1. When rocks are forced below the earth’s surface they are squeezed and heated so much that they change.
What kind of rock is this?
2. What word means "change?"
1. Metamorphic rock.
2. Metamorphic means to “change”.
What are the two most dangerous things about volcanoes?
The toxic gas and the heat from the air/lava.
