What best defines Earth Science?

• It is the study of the Earth's structure, properties, processes, and four and a half billion years of biotic evolution.   

What is Geology?

• is the study of the origin, history, and structure of Earth. It includes the study of the processes that shape Earth.

What do the O, A, E, and B horizons together form?

• Solum

• 
  
  

What is geothermal energy?

b) Heat from Earth's interior used to heat buildings and generate electricity

What is the most common type of hydroelectric power plant?

b) Dam-based power plant

Geothermal energy is best found in areas with:

b) High thermal gradients

What is a potential drawback of geothermal energy?

b) It can be non-renewable if extraction rates exceed replenishment rates

What is ore?

• is the study of the origin, history, and structure of Earth. It includes the study of the processes that shape Earth.

What portion of the Earth's surface is covered by water?

C) 70%

Order of how ores are formed.

• Crystal settling, Hydrothermal processes, Pegmatization, Precipitation, Placer, Weathering & Groundwater Action.

 
What is Quartz used for?

• primarily used in the manufacture of glass.
  
  
  

What is true about Gypsum?

• used as retarder in Portland cement.
  
  

One is false about Calcite

• is an important component of metallurgical products,

Which are steps to mitigate exploitation of minerals. 

• Responsible mining practices, Conservation, Recycling.

Country where Bauxite is used.

• Jamaica

What ore is used for automobiles?

• Hematite

Silver is used for?

• Coins

The United States uses this ore often.

• Silver

What is geothermal Energy?

• A natural heat from the interior of the Earth that is converted to heat.

Are processes that are formed or occurring beneath the surface of the Earth.

• Endogenic Process

How are magma formed?

• Process by partial melting of earth’s lower crust

Which is NOT possible when melting occurs in the mantle.

• Earth’s rotation is faster.

Which is True about Metamorphism

• A process that leads to changes in mineral contents.

Types of Metamorphism:

• Contact and Regional

What happens in Regional Metamorphism 

• A change in the rock happens in a larger area, a large-scale action of heat and pressure.

Agents of Metamorphism except one:

• Density

Factors in affecting change of rocks:

• Stress, Strain, Joints, Faults.

Types of Fault except one:

• Slide slip Fault

If the wall moves down relative to the footwall, in a way you would normally

expect as a result of gravity. What kind of Fault is it?

• Normal Fault

When the fault blocks with each other horizontally. What kind of Fault is it?

• Strike slip Fault

The hanging wall moves up relative to the footwall. What kind of Fault is it?

• Reverse Fault

Fractures in rocks that show little or no movement at all.

• Joints

The ability of a rock material to handle stress depends on the elasticity of the rocks.

• Strain

The force that could create deformation in rocks in their shape and volume.

• Stress

Two types of Weathering:

• Chemical and Mechanical

What best defines rocks:

• Naturally formed solid made up of one or more kinds of minerals.

Rocks that form when lava cools and becomes solid are?

• Extrusive

Rocks that form when magma solidifies within the crust are?

• Intrusive

The process of transporting the weathered material, eventually depositing it in new

location or environment.

• Erosion

Rocks, grains of sand, and silt collide with one another when currents or waves carry

them along a stream or beach.

• Abrasion

Water accumulates in a crack and then freezes, the ice expands.

• Frost wedging 

Rocks at Earth’s surface are exposed to daily and yearly

cycles of heating and cooling. What may happen to the rocks?

• They expand when they are heated and contract when they cool.

After erosion what process happens next?

• Deposition

What are the 3 main types of rocks?

• Igneous, Sedimentary, Metamorphic

What best defines a Mineral?

• A naturally occurring, inorganic crystalline solid element or compound composed of an ordered arrangement of atoms with a specific chemical composition.

 If the minerals break in an uneven way what might have happened?

• Fracture

A miner has mined 2 tons of Feldspar. What classification should it be sorted to?

• Silicates

The wife’s ring is made up of a native elements. What mineral is it made of?

• Graphite

When checking on the mineral in rock it is something that is least used.

• Color

A miner has smelled a rotten egg in the mines. What mineral might these be?

• Zinc Sulfide

My dish tasted a little bland. What mineral should I use to make it tastier?

• Halite

The animals in the park are standing in what part of the Earth?

• Lithosphere 

What is planet Earth called sometimes?

• The Blue Planet

It is the protective layer of the earth that protects us from the sun's radiation.

• Ozone Layer

Which layer of the Atmosphere is the Ozone Layer located?

• Stratosphere

Do dead organic matter count as part of the Biosphere?

• Yes

While walking looking at the telescope you spotted our neighbor galaxy Andromeda, you wondered how old is our own galaxy “Milky Way”?

• 13.8 Billion

What was the main concern of SNT?

• The angular momentum of the sun

According to SNT, what triggered the condensation of the interstellar gas and dust clouds?

• Supernova Explosion

What happens to the gas and dust clouds after it collapses due to gravity?

• It becomes a protostar

What does the secondary whirlpool motion of Vortex Theory explain?

• The orbit of satellites

What happens to the debris from the collision in the Collision Theory?

• It formed planets that rotate in the same direction as they revolve around the sun

What formed the sun and planets according to the Kant Laplace Theory?

• The bulges in the collapsing cloud
