What layer of the Earth is made of liquid metal that rotates and generates Earth's magnetic field?
Inner Core
Mantle
Outer Core
Crust
Which of the following is correct?
Metamorphic rocks form from intense heat and pressure that occurs beneath Earth's surface.
Igneous rocks form from sediments compacting and cementing together.
Sedimentary rocks form from lava cooling.
Metamorphic rocks form from weathering and erosion.
Mountains form ....
at convergent boundaries where two plates meet head on.
at divergent boundaries where two plates move away from each other.
at transform boundaries where two plates slide past each other.
where igneous rocks pile up after volcanic eruptions.
At which type of plate boundary interaction do earthquakes occur most frequently?
transform boundaries where plates slide past each other.
transform boundaries where plates move away from each other.
convergent boundaries where two plates push into each other.
divergent boundaries where two plates slide past each other.
Which layer of the earth is known for being the thinnest and having the lowest density?
Mantle
Outer Core
Crust
Inner Core
Which of the following best explains how volcanoes form on Earth?
Volcanoes form from transform boundaries where plates slide past each other.
All mountains are potential volcanoes if an opening forms at the top.
At divergent boundaries where plates pull apart from each other allowing magma to rise to the surface.
At subduction zones where tectonic plates are pushed/pulled by the convection currents in the mantle.
What type of heat transfer occurs in the mantle of the Earth that is responsible for pulling/pushing tectonic plates like a conveyor belt?
convection
conduction
radiation
subduction
At which plate boundary would new oceanic crust form?
New (young) oceanic crust never forms.
convergent; plates push into each other creating a new seafloor
divergent; magma rises and cools to form a new seafloor
transform; plates slide past each other forming a new seafloor
Which of the following best describes convection currents in the mantle?
Hot rocks expand and rise towards the crust, cool rocks sink towards the outer core.
Cool rocks expand and rise towards the crust, hot rocks sink towards the outer core.
When two plates push into each other this is called a _________ boundary, which forms __________.
convergent; earthquakes
convergent; mountains
divergent; mid-ocean ridges
transform; earthquakes
Where are volcanoes most likely to form?
The middle of a plate, specifically on land
along plate boundaries (where two different plates meet)
The middle of a plate, specifically under water
What is a tectonic plate?
A huge chunk of dense ice that slowly moves.
A rapidly rotating column of air that moves through a storm and destroys things in its path.
A storm with violent wind that travels through the ocean and destroys things in its path.
A large division of Earth’s crust that moves over time.
Which of the following explains why tectonic plates cause geologic processes? Select ALL that apply...
As plates move over the surface of the earth, they disrupt the gravitational pull Earth has on the moon, causing violent storms to form in the ocean.
As plates move over the surface of the earth, they move countries into new locations which rapidly changes the climate of those countries.
As plates move over the surface of the earth, they shake the surface which can create disasters such as hurricanes, tornadoes, earthquakes, tsunamis, and floods.
As plates move over the surface of the earth, they interact in ways such as sliding over each other creating volcanoes, separating from each other creating trenches, etc.
As plates move over the surface of the earth, they can slide past each other creating mountains and glaciers in their paths.

A line of volcanic activity stretches across the country of Iceland. What is the most likely reason that there are so many volcanoes in Iceland?
Iceland is on a border between two tectonic plates.
Iceland is in the northern hemisphere.
Iceland has drilled deep wells to create the volcanoes.
Iceland has a cold climate that needs volcanoes to keep it warm.
The diagram below shows a stack of rock layers. These layers have not changed position since they formed.
The fossils in Layer 2 are younger than those in Layer 1 and older than the fossils in Layer 5
The fossils in Layer 2 are older than those in Layer 1 and younger than the fossils in Layer 5
The fossils in Layer 2 are older than those in Layer 5 and younger than the fossils in Layer 4
The fossils in Layer 5 are older than those in Layer 4 and younger than the fossils in Layer 1
The diagrams below represent rock layers found in two different locations by two different scientists. The scientist at location X used letters to label his rock layers, while the scientist at location Y used roman numerals to label her layers. Examine these diagrams and then answer the question that follows. The scientists both used the same colors and patterns to represent different types of rocks. They also used the same set of black-and-white symbols to represent specific types of fossils in the layers. By correlating layers based on fossils and rock types, the two scientists have discovered that certain rock layers are present in both locations. Based on this information, if the age of layer R is 260 million years, then what other layer likely also has an age of 260 million years?
S

Q
