What is the correct order from inside to outside of Earth’s layers?
crust,core,mantle
core mantle crust
crust core mantle
What is the difference between the asthenosphere and lithosphere?
asthenosphere includes the crust and the solid part of the upper mantle lithosphere is the outer part of the mantle made up of semimolten rock
asthenosphere includes the crust lithosphere is the outer part of the mantle made up of semimolten rock
Asthenosphere is the outer part of the mantle made up of semi-molten rock and the lithosphere includes the crust and the solid part of the upper mantle
Describe plate tectonics.
Plates (lithosphere) are constantly moving on top of the asthenosphere. Volcanoes and earthquakes occur at plate boundaries.
Plates (lithosphere) are constantly moving on top and bottom of the asthenosphere. Volcanoes and earthquakes occur at plate boundaries.
Plates (lithosphere) barely move on top of the asthenosphere. Volcanoes and earthquakes occur at plate boundaries.
Describe convergent, divergent, and transform plate boundaries and give an example of a physical feature for each type of plate boundary.
Divergent – plates collide into each other
Convergent – plates move part from each other
Transform – plates rub or scrape each other
Divergent – plates move apart from each other
Convergent – plates collide into each other
Transform – plates rub or scrape each other
Divergent – plates rub or scrape each other
Convergent – plates collide into each other (example – subduction)
Transform – plates move apart from each other (example – earthquakes and faults)
What is the ring of fire?
Active ring of volcanoes around the Pacific Ocean
active ring of volcanoes around the north pacific ocean
Define fault.
Boundary where two plates slide against each other
boundary where three plates slide against each other
At which type of plate boundaries do volcanoes usually occur?
transform and convergent boundaries
Convergent and divergent boundaries
divergent and transform boundaries
How do major volcanic eruptions affect the temperature on Earth?
SO and other particles form a haze (cloudiness) that blocks sunlight and causes global temperatures to decrease
SO2 and other particles form a haze (cloudiness) that lets sunlight and causes global temperatures to decrease
SO2 and other particles form a haze (cloudiness) that blocks sunlight and causes global temperatures to decrease
Describe the difference between focus and epicenter regarding earthquakes.
Focus – the point underground at which the earthquake originates
Epicenter – the point on the surface at which the earthquake originates
epicenter – the point underground at which the earthquake originates
focus – the point on the surface at which the earthquake originates
Define minerals and rocks.
Minerals – naturally occurring inorganic solid elements and compounds with crystalline structure
Rocks – a combination of one or more minerals
Minerals – naturally occurring inorganic solid elements and compounds with crystalline structure
Rocks – a combination of two or more minerals
Define weathering and give examples of biological, chemical and physical weathering.
physical – external process that wears down rock to smaller individual particles
Biological – tree roots and lichens
Chemical – water, acids
weathering – wind, rain
Weathering – external process that wears down rock to smaller individual particles
Biological – tree roots and lichens
Chemical – water, acids
Physical – wind, rain
Describe the difference between weathering and erosion.
Weathering is when rocks are broken down into smaller and biggest particles and erosion is when those particles are moved or carried away
Weathering is when soil broken down into smaller particles and erosion is when those particles are moved or carried away
Weathering is when rocks are broken down into smaller particles and erosion is when those particles are moved or carried away
Describe the three types rock in the rock cycle and how each type forms.
Sedimentary – sediments become compacted after deposition (the accumulation of sediments/particles)
Igneous – rock made from the cooling of magma
Metamorphic – compressed sedimentary rock that undergoes high heat and pressure (lithification)

metamorphic – rock made from the cooling of magma
igneous – compressed sedimentary rock that undergoes high heat and pressure (lithification)
Is soil considered a renewable or nonrenewable resource? How long does it take?
Soil renews very slowly over thousands of years
Soil very fast
What are the four main components of soil?
Minerals, organic , air and water
Minerals, organic matter, air and water
What is humus?
Porous mixture or partial decayed plants and animals (organic matter)
Porous mixture or plants and animals (organic matter)
What is the order of soil horizons from top (surface) to bottom? Briefly describe each horizon. A, C, R, O, B
O – organic material (plant/leaf litter) not decomposed yet
b – contains humus, stores water and nutrients, topspoil
r – rocks, clay and sand not all the way broken down
C – rocks that are partially weathered
a - bedrock; rocks that are not broken down at all
O – organic material (plant/leaf litter) not decomposed yet
A – contains humus, stores water and nutrients, topspoil
B – rocks, clay and sand not all the way broken down
C – rocks that are partially weathered
R- bedrock; rocks that are not broken down at all
What are five causes of soil erosion?
Logging, construction, off road vehicles, overgrazing, farming
Logging, construction, off road vehicles, overgrazing,
Describe the three basics steps of mining.
1) Remove chunks of rock from the ground
2) Remove ore from rock
3) Remove mineral from the chunks of rock from the ground
1) Remove large chunks of rock from the ground
2) Remove ore from rock
3) Remove mineral from ore
Describe an ore.
An ore is a chunk of rock that contains a valuable minera
An ore is a chunk of rocks
Describe three types of surface mines
Place mines – minerals are removed from sand and gravel from rivers
Strip mines – large machines strip away unwanted rock to obtain the minerals
Open pit mine – (quarry) machines are used to make large holes
strip mines – minerals are removed from sand and gravel from rivers
place mines – large machines strip away unwanted rock to obtain the minerals
Open pit mine – (quarry) machines are used to make large holes
List three characteristics of subsurface mining that make it different from surface mining.
Subsurface mining is more dangerous
Subsurface mining has less environmental impact
Subsurface mining is more expensive because of safety and construction costs
Subsurface mining is less dangerous
Subsurface mining has less environmental impact
Subsurface mining is more expensive because of safety and construction costs
What is smelting?
Heating ore and rock to separate the desired metal
Heating ore to separate the desired metal
What are tailings?
A crushed mixture of rocks of the unwanted part ore
A crushed mixture of the unwanted part ore
What are four environmental impacts of mining?
Air pollution
Water pollution

Explain acid mine drainage and its effect on the environment.
Acid mine drainage occurs when acidic water drains out of an abandoned mine. The exposed rock after mining reacts with water and oxygen to form sulfuric acid. The acid dissolves toxic heavy metals that pollute ground and surface water.

Describe the Surface Mining Control and Reclamation Act of 1977 and the term reclamation.
The Surface Mining Control and Reclamation Act of 1977 requires mining companies to restore the land after mining
