The rock type most likely being formed in Iceland is shown in the diagram is-
metamorphic
intrusive
igneous
sedimentary
The Hawaiian Islands are positioned over a hotspot in the middle of the Pacific Ocean, which is a location on a tectonic plate where magma pushes up through the crust from the mantle. There is regular volcanic activity on the islands, in which magma erupts as lava, but often parcels of magma rise and remain trapped below the surface of the earth. Which type of rock could a geologist expect to find deep below an inactive volcano on the Hawaiian Islands?
sedimentary: the rocks would have cooled quickly in the Earth’s crust
Metamorphic: the rocks would have cooled slowly in the Earth’s crust
Intrusive Igneous: the rocks would have cooled slowly in the Earth’s crust
Extrusive Igneous: the rocks would have cooled quickly in the Earth’s crust
A geologist studying volcanic activity is collecting rocks that formed from hot, molten magma. What type of rock is the geologist collecting?
Clastic Sedimentary
metamorphic
Chemical Sedimentary
Igneous
The horizontal structure shown in the rock formation 3 is called a-
sill
inclusion
extrusion
dike

A student examines 2 maps which show the distribution of Glossopteris fossils across Pangaea, and across the current location of continents. What is the most likely cause of the separation of the fossils, and the geographic evidence for it?
the subduction of 1 plate under another caused the separation, & a continuous trench would serve as evidence.
seafloor spreading caused the separation, & a line of volcanoes along Africa would serve as evidence
the subduction of one plate under another caused the separation, & a line of islands would serve as evidence
seafloor spreading caused the separation, & a mid-ocean ridge would serve as evidence
What type of stress is shown?
uplift
shearing
compression
tension
When the sea floor spreads apart, volcanoes and ridges are formed because-
sediments are deposited where the floor spreads, building ridges
ocean water pushes down on the surrounding sea floor, pushing up ridges
underwater earthquakes lift the sea floor into long ridges
as the plates pull apart, magma moves to the surface, building ridges
Which city was located the closest to the epicenter?
New York
Buffalo
Boston
Montreal
Which provides the best evidence for the theory that faults and volcanoes are a results of tectonic plate interactions?
faults and volcanoes existed long before there were tectonic plates
faults and volcanoes are often found at tectonic plate boundaries
faults on tectonic plates are in constant motion, but volcanoes may not erupt for many years
tectonic plates that have many faults do not usually have volcanoes.
Look at the diagram. According to the diagram, the crust is moving due to-
radiation
conduction
tension
convection
What causes an abundant amount of earthquakes to originate around the Japanese islands?
the islands of Japan are situated on top of a large amount of magma.
the islands of Japan are unstable volcanic landforms that is highly active.
the islands of Japan are located on the meeting point of several plate boundaries.
the islands of Japan have a mountainous terrain surrounded by water.

Identical rock types, identical fossils, are very similar mountain ranges are found on different continents that are separated by a wide ocean. Which of these best explains these observations?
organisms traveled between these continents on land bridges.
these continents were joined together at one time in the past.
the same forces erode mountains in different locations.
some rock types are very common and are found everywhere.
The map depicts the boundary between the Arabian Plate and the African Plate. The relative plate motion is indicated by the arrows in the map. Which of the following best describes the type of plate boundary depicted in this map?
divergent
subduction
transform
convergent
Which type of fault is shown?
strike-slip
normal
reverse
thrust
A continental-oceanic boundary where plates collide is called a-
subduction zone
sublimation boundary
thrust boundary
transform boundary
A student studies a map provided by the USGS (United States Geological Survey) where each red dot represents and active volcano. What can the student conclude about the occurrence of volcanoes?
all volcanoes occur at the plate boundary
all volcanoes can be found in a mountain range
most volcanoes occur at a plate boundary
most volcanoes occur at a lake or bay
Which layer of the Earth is the hottest?
liquid out core
crust
mantle
solid inner core

Which item of data would best support the theory that the North and South American continents are moving in a different direction from the African and Eurasian continents?
the flow of currents between the American and African and Eurasian continents form a cyclic pattern
the presence of volcanic activity at the Mid-Atlantic Ridge is constantly creating new seafloor
the eastern coastline of Africa seems to fit the western coastline of South America
the western coastline of Africa seems to fit the eastern coastline of South America
Compared to the Rocky Mountains, the Appalachian Mountains are much-
less eroded
thicker
older
higher

According to the diagram, the Ring of Fire is shown by the outline of the –
African Plate
Eurasian Plate
Pacific Plate
South American Plate
What best describes the process of subduction?
the formation of a fault when 2 plates meet & both plates sink at the same time, creating a chasm between them
the process of more dense plate sinking beneath a less dense plate during a tectonic collision
the procession of tectonic plates pulling away from one another leaving cracks between them
the process of 2 places that hold land masses colliding causing both plates to shift upward forming a mountain range
