Geologists have classified rocks into three major groups of rocks which are:
inorganic, organic and chemical rocks
igneous, sedimentary and metamorphic rocks
metamorphic, chemical and non chemical rocks
sedimentary, inorganic and igneous rocks
Any rock that forms from another rock as a result of changes in heat or pressure (or both) is a:
chemical rock
igneous rock
sedimentary rock
metamorphic rock
You find a deposit of organic limestone. In what type of rock setting did it probably form?
the ocean
a volcano
a swamp
sand dunes
A rock that forms from many small fragments of other rocks is a(n)
igneous rock
metamorphic rock
sedimentary rock
extrusive rock
The process by which metamorphic rock changes to igneous rock begins with
melting
erosion
deposition
crystallization
If heat and pressure inside Earth cause the texture and crystal structure of a rock to change, what new material is formed?
sedimentary rock
metamorphic rock
igneous rock
chemical rock
Boundary between two colliding plates, often associated with mountain building, ocean trenches and volcanic islands
plate boundary
magma
divergent boundary
convergent boundary
A hot spot is located at the boundary of a plate
true
false
Which of the following will move with time ?
a hot spot
the plate the hot spot is over
neither move
both move
What is a Hot spot?
Is an area of Earth that sits over a mantle plume.
A place where people can access internet.
A large mountain that creates major landslides.
A spot where a basketball player is good at shooting.
Where do trenches form?
Divergent
Convergent
Transform
Hot Spots
Paleomagnetism was used to confirm sea floor spreading because it showed
Patterns or polar reversals in the seafloor that was identical on either side of the mid ocean ridge
The magnetic north pole was at one time in the Atlantic Ocean
Cosmic radiation being deflected by the Earth’s magnetic field lead to fracturing the continents
The oldest rock on the ocean floor is closest to the mid ocean ridge
P waves travel (check the 2 that are correct)
longitudinally
up and down
through solids only
twice as fast as S waves
What is a sinkhole?
A hole formed when limestone is dissolved (WATER) and ERODED causing the land above to collapse.
A pile of sediment and rocks that has been eroded then DEPOSITED by a glacier (ICE)
the sudden movement of rock and soil down a slope caused by GRAVITY, heavy rains (WATER), cutting down trees, construction on steep slopes, and/or earthquakes.
Pollution (sulfuric acid) from factories dissolves in precipitation; a cause of CHEMICAL weathering when the acid eats away at rocks and buildings.
Why are sinkholes common in Florida?
Florida is a peninsula. Sinkholes are commonly formed on peninsulas because a peninsula is surrounded by water.
Florida has a lot of swamps with animals that burrow into the sandy soil making holes and tunnels that collapse.
Florida's underlying rock is limestone. Limestone dissolves easily, forming caverns which can then collapse and form a sinkhole.
Florida has a lot of oil underground. When the oil is removed, there is nothing left to hold up the soil
How does acid rain cause weathering?
through abrasion
though oxidation
by dissolving rock
by carrying rock away
Check all of the statements that are correct about Florida's landscape.
It is likely to find sinkholes in Florida because it sits on a bed of limestone that can be chemically weathered away.
Florida has dunes, marshes and swamps.
Florida's lakes were formed by melting glaciers 100,000 years ago.
Florida has low-lying wetlands such as the Everglades.
Which type of rock is made from lava or magma cooling?
igneous
sedimentary
metamorphic
Tiny bits of weathered rock or once living plants or animals are called
Sediment
basalt
mineral
coal
When the force of gravity pulls a lithospheric plate downward and away from a ridge pushing it toward a trench.
Sea Floor Spreading
Subduction
Ridge Push
Slab Pull
