Geology Terms
100
a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
What is a Volcano
100
The top layer of the Earth's surface
What is the crust
100
naturally occurring solid
What is Rock
100
the result of a sudden release of energy in the Earth's crust that creates seismic waves
What is Earthquake
100
the continuous movement of water on, above and below the surface of the Earth
What is The Water Cycle
200
Volcanoes are not randomly distributed over the Earth's surface. Most are concentrated on the edges of continents, along island chains, or beneath the sea forming long mountain ranges. More than half of the world's active volcanoes above sea level encircle the Pacific Ocean to form the circum-Pacific.
What is The Ring of Fire
200
When two plates collide, some crust is destroyed in the impact and the plates become smaller. The results differ, depending upon what types of plates are involved.
What is Convergent Plate
200
types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water.
What is Sedimentary
200
Earthquakes are measured using observations from?
What is Seisometers
200
the science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change
What is Geology
300
This is a Stratovolcano
What is Mount Fuji
300
Seafloor spreading is the movement of two oceanic plates away from each other, which results in the formation of new oceanic crust (from magma that comes from within the Earth's mantle) along a a mid-ocean ridge.
What is Divergent
300
formed through the cooling and solidification of magma or lava
What is Igneous
300
waves of energy that travel through the Earth's layers, and are a result of an earthquake, explosion, or a volcano that imparts low-frequency acoustic energy.
What is Seismic Wave
300
system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history.
What is Geologic Time Scale
400
mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth
What is Magma
400
Places where plates slide past each other
What is Transform Boundries
400
The scientific study of rocks
What is Petrology
400
series of water waves caused by the displacement of a large volume of a body of water, generally an ocean or a large lake.
What is Tsunami
400
the science of determining the relative order of past events, without necessarily determining their absolute age
What is Relative Dating
500
Molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling.
What is Lava
500
The plates make up Earth's outer shell
What is lithosphere
500
The aggregate minerals forming the rock are held together by?
What is Chemical Bonds
500
the point on the Earth's surface that is directly above the hypocenter or focus, the point where an earthquake or underground explosion originates.
What is Epicenter
500
horizontal units that are internally composed of inclined layers
What is Cross- Bedding
