3
What do continental-continental collisions form?
large mountain ranges
island chains/arcs
hot spots
volcanic mountain ranges
4
As rivers slow down, what happens to sediments?
They increase mass movement
They increase erosion
They dissolve faster
They increase deposition
5
Which one is NOT one of the 4 major spheres of the Earth?
Geosphere
Hydrosphere
Lithosphere
Biosphere
6
If something is found buried next to/with an index fossil, you would know
it ancient ecosystem
its classification
it feeding relationship
its geologic age
7
In a geologic column, the youngest rocks are found
buried under fossil layers
at/near the surface
in the deepest layers
at the mouths of rivers
8
What feature is formed when two ocean plates collide?
trench
underwater mountain (seamount)
hot spot
midocean ridge
9

Cenozoic, Jurassic, Paleozoic
Paleozoic, Cenozoic, Mesozoic
Mesozoic, Cenozoic, Paleozoic
Paleozoic, Mesozoic, Cenozoic
10
What causes convection currents in the mantle?
differences in temperature & density
subduction
ridge push and slab pull
continental movement
11
What would cause new oceanic crust to be made?
subduction at a convergent boundary
transform boundaries
magma rising at a divergent boundary
continental-continental collisions
12
What type of fossils are usually found in only 1 layer?
index fossils
trace fossils
molds
petrifactions
13
Approximately, how old is the planet Earth?
less than 10,000 years old
4 million years old
4.6 billion year old
450 million years old
14
Convection Currents move material in the
Mantle
Crust
Core
Lithosphere
15
Why does oceanic crust subduct under continental crust?
Continental crust is too dense
Ocean crust is less dense
Continental crust is thicker
Ocean crust is more dense
16
A missing period of geologic time in a rock sequence is called a/an:
Intrusion
Extinction
Cast
Unconformity
17
Biological action, like a tree root growing into a rock, would be an example of
differential weathering
mechanical weathering
chemical weathering
spheroidal weathering
18
Where are the youngest rocks of the ocean found?
next to continents
on island arcs
in the deep sea trenches
at midocean ridges
19
New ocean floor is made in a process called
sea floor spreading
subduction
weathering
mass movement
20
What force causes more weathering and erosion than any other?
Gravity
Running water
Wind
Glaciers
21
The Hawaiian Islands were formed by
a trench
a rift valley
a hot spot
a midocean ridge
22
Why haven't we found rocks as old as the Earth?
Subduction/weathering have recycled them
They have evaporated
They have been destroyed to make goods
They are buried too deep
23
The continuous change of rocks from one kind to another is called
stratification
rock cycle
lithification
crystallization
24
As a result of human activity, the amount of sediments carried by rivers and streams has
decreased
increased
stayed the same
stopped completely
25
The Lithosphere is divided into large moving slabs according to
Plate Tectonics
Rock Cycle
Principle of Uniformitarianism
Law of Superposition
26
Magnetic "stripes" on the ocean floor are caused by:
continental movements
reversals of the Earth's polarity
subduction of old ocean crust
convection currents
27
What are the 3 main parts to the Geosphere?
Lithosphere, Asthenosphere, Core
Crust, Mantle, Core
Hydrosphere, Lithosphere, Core
Crust, Lithosphere, Core
28
What evidence best helps scientists to conclude there are different layers in Earth?
Earth's rotation on it axis
Volcanic eruptions
Seismic waves and shadow zones
Mountain building
29
What mass extinction event likely ended the Mesozoic Era (Age of Reptiles)?

Heat & Pressure
31
Where do the MOST earthquakes happen?
in volcanic mountain ranges
in trenches where plates collide with eachother
along sea floor edges
At midocean ridges where spreading occurs
32
How do scientists determine the age of a rock or fossil?
study the mineral content
study the radioactive isotopes
count the layers above it
study the diversity fossils
33
Which is NOT a Fossil Fuel?
Coal
Natural Minerals
Oil
Natural Gas
34
The process of determining the sequence/order of past geologic events is called
absolute dating
relative dating
virtual dating
radioactive dating
35
How are metamorphic rocks made?
cooling of magma
water evaporating leaving crystals behind
compacting and cementing sediments
heat and pressure inside the Earth
36
Where do fossil fuels come from?
chemical reactions in atmosphere
preserved remains of living things
molten rock flows over land
radioactive decay of sediments
37
What layer generates the magnetic field?
Core
Mantle
Crust
Lithosphere
38
Where in the world is there a strike-slip/transform boundary?
the San Andreas Fault
the Peru-Chile trench
the Midatlantic Ridge
Great Rift Valley of East Africa
39
What is a difficulty of using radioactive dating with sedimentary rocks?
they are usually too young in age
particles are made of different, older rocks
they can fold and fault
they might weather faster
