Tectonic Plates
What is divergent boundary?
Two plates pull away/apart from each other
Word for - a preserved remains of an organism that used to live in the past
Fossil
What is a mineral?
An inorganic solid that has a crystal structure and a definite chemical composition.
What is granite?
A light-colored rock that is found in continental crust.
What is Intrusive Rock?
Igneous rock that forms when magma hardens beneath Earth's surface.
What is the difference between divergent and convergent?
Convergent is when plates move towards each other, but divergent is when they pull apart.
What happened to the Pangaea?
a single landmass that broke apart about 200 million to 300 million years ago; broke apart because of tectonic plates.
How do minerals form?
What is Rock-forming minerals?
Any of the common minerals that make up most of the rocks of Earth's crust.
What is Extrusive Rock?
Igneous rock that forms from lava on Earth's surface.
What happens as plates move?
Earthquakes, volcanoes are formed, mountain ranges are formed, deep ocean trenches are formed.
What is a Continental Drift?
The hypothesis that the continents slowly move across Earth' surface
How are Minerals identified?
Each mineral has characteristic property that can be used to identify it.
Difference between basalt and granite?
The texture, color and composition.
Difference between Extrusive Rock and Intrusive Rock
Cooling location and the way they form.
What happens when subduction occurs?
More dense oceanic crust sinks, water leaves the sinking crust and rises into the wedge of the mantle above.
What is the continental drift theory?
Parts of the drift on top of the liquid core.
What does crystallization do?
Transformed liquids, or gases to a solid crystal structure.
What is the metamorphic rock?
A type of rock that forms from an existing rock that is changed by heat, pressure or chemical reactions.
What is the texture of Igneous Rock?
What do convection currents do?
Causes the plates to move, plates collide,
What is the Scientific Method?
Step by step process used to investigate questions, gather evidence, and solve problems about the natural world.
What is the difference between a mineral and a crystal?
Mineral is defined by what it is made of while a crystal is defined by its structure.
How do Geologists Classify Rocks?
Observe the rock's mineral composition, color and texture.
How are Igneous Rocks used?
People throughout history have used igneous rock for tools and building materials.
