Dynamic Earth Flashcards
Hot molten material that flows from beneath the earth’s crust onto the surface, usually from volcanoes; it cools to form volcanic rock.
Lava
A type of rock formed by the cooling and hardening of magma or lava.
Igneous rocks
Molten rock within the Earth.
Magma
The slow process in which rocks are constantly being formed and changed from one type to another.
Rock cycle
The type of rock formed from other rocks by the action of heat and pressure
Metamorphic rocks
The slow physical and chemical breakdown of rocks by the action of rain, cold.
Weathering
A type of rock formed by the cementing together and hardening of sediments.
Sedimentary rocks
A substance obtained by mining
mineral
And upward fold in rock formed by compression of Earth’s crust.
Anticline
A highly vicious, mechanically week and deforming region of the upper mantle of the earth. It lies below the lithosphere
Asthenosphere
The movement of the earth’s continents drifting across the ocean bed.
Continental drift
The centre part of the earth
Core
The outermost solid shell of a planet.
Crust
The vigorous shaking of the earth which can be violet enough to destroy major buildings and kill thousands of people.
Earthquake
The point of the Earth’s surface that is directly above the hypo centre or focus which is also the point where an earthquake originates.
Epicentre
Where two blocks of rock converge towards each other, therefore creating a hanging cliff.
Reverse fault
We are two blocks of rock diverge by tension and therefore creating a hill or mountain.
Normal fault
A fault in which two blocks of rock are displaced mainly in a horizontal direction, parallel to the line of fault.
Strike-Slip fault
A crack in a rock which is slipped.
Fault
The buckling of rocks caused by huge Earth forces.
Fold
A Scientist who studies the solid and liquid matter.
Geologist
An Earth science comprising the study of Earth, the rocks of which it is composed, and the processes by which they change.
Geology
The magnitude of an earthquake, usually expressed by the Richter scale, it is a measure of how big the waves are.
Richter scale
The region of the interior of the earth between the core and the crust. It is 2000 miles thick.
