heat and pressure
melting
uplifting
evaporation
2
Index fossils are found in...
multiple layers, one location
multiple locations, one layer
I don't know
3
a form of chemical weathering is
a sinkhole
abrasion
acid rain
ice wedging
4
Define: Rock Cycle
A process that slowly change rocks from one kind to another
A process that quickly change rocks from one kind to another
Only happens to igneous rocks
Happens to only chemical rocks
5
Which statement is true about the fossils in the diagram?
fossil in Layer X is the oldest.
fossil in Layer Y is older than the fossil in Layer Z
fossil in Layer Y is older than the fossil in Layer X
fossil in Layer Z is the youngest
6
How are Metamorphic Rocks formed?
Weathering & Erosion
Compacting & Cementing of Sediment
Heat & Pressure deep inside Earth
Cooling & Hardening of Magma
7
What caused the mass extinction of dinosaurs?
Global Warming
Asteroid impacts, climate change, volcanoes
Humans
The black hole
8
what is a tsunami
some cool wave that would be rad to surf on
a long high wave caused by an underwater earthquake
a small wave that hits the beach
a shaking in the ground
9
The law of super position states that.....
Igneous intrusions are made of sedimentary rock
Plate tectonics do not affect the rock layers
Cross cutting sections are older than rocks they cut through
Rock layers are formed one on top of the other; youngest top-oldest bottom
10
a form of physical weathering is
plant roots
water erosion
wind erosion
ice wedging
11
Which describes the relationship between earthquakes and volcanoes?
Earthquakes usually cause volcanoes to erupt.
Volcanic eruptions usually cause severe earthquakes.
Earthquakes and volcanoes are not related in any way.
Earthquakes & volcanoes often are located where plates meet.
12
How does Volcanoes impact the atmosphere (air)?
I thought volcanoes only exploded and killed people.
Volcanoes clean the air with all the ash and CO2 and water.
Pollution of air and water, big release of carbon dioxide.
Volcanoes have no impact on the atmosphere
13
The principle of cross cutting is when
Rocks that cut across another rock are the same age
Rocks that cut across another rock is older
Rocks that cut across another rock is younger
14
Folding or faulting?
Folding
Faulting
15
What is an index fossil?
A fossil of an organism that lived a short period of time
A fossil only found in one location
A fossil found on the top layers
A fossil of an important organism
16
How do Igneous rocks form?
Heat & Pressure deep inside earth
weathering and erosion
Compacting & Cementing
Cooling and hardening of magma/lava
17
How is the movement of the two continents shown best explained?
magnetic changes
volcanic eruptions
plate tectonics
coastal flooding
18
How are Sedimentary Rocks formed?
Cooling & Hardening of Magma
Heat & Pressure Deep within Earth
Cementing & Compacting of sediment
Weathering & Erosion
19
The instrument that records earthquake waves
pictograph
seismograph
baramoter
thermometer
20
If these layers have not been overturned, what can you conclude about the age of the fossil?
It Is older than the shale
It is younger than the sandstone
It is older than the sandstone
It is younger than the shale
21
What drives the rock cycle? (
all cycles on Earth
)
Ground movement
Heat
Pressure
Erosion
22
Click the definition of: Intrusive Igneous Rock
An Igneous rock that forms, and stays under ground.
An Igneous rock that is not under ground.
A rock that blows up from the inside.
A rock that rides a bike.
23
What is Erosion?
The movement of sediments or rock to one place or another.
When rock sediments are transformed into another rock.
The breaking down of rocks.
The wearing down of rocks.
24
A boundary where two plates come together, or collide, is called a
convergent boundary.
transfer boundary.
transform boundary.
divergent boundary.
25
What kind of boundary is at a mid ocean ridge?
state
convergent
transform
divergent
26
Which layer of Earth contains the asthenosphere?
crust
mantle
outer core
inner core
27
what can happens at divergent boundaries
plates collide and form volcanic mountains
plates stop moving & create a hot spot
plates slide past each other
plates move apart, magma rise, & volcanoes form
28
What is relative dating?
The timing of two things compared
None of these
The age difference between two related things
The approximate age of something in relation to what surrounds it
29
The theory of plate tectonics attempts to explain the
layering of sedimentary rock.
movement of Earth's upper layers.
gravitational forces of Earth.
composition of Earth's inner regions.
30
What causes the crustal plates of the earth to move?
the prevailing winds in the jet stream
the rotation of the Earth on its axis
convection currents in the mantle
the high tides of the oceans
31
Rock layer X at location B is most likely the same relative age as which rock layer at
1
2
4
3
32
Which rock layer is the youngest?
limestone
shale
sandstone
basalt
33
When two tectonic plates slip or slide past one another, what type of boundary is it called?
state
divergent
convergent
transform
34
How are earthquakes most likely to occur?
one crustal plate moves under another
bubbles of magma rise to the surface
the pressure cracks thin areas of the crust releasing energy
heat causes the mantle to expand
35
Which of the following is an accurate description of the Earth's crust
rocky & brittle
