Scientists recently discovered that rocks collected from the Franklin Mountains in West Tests and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of--
coastal erosion
plate tectonics
ocean currents
glacial melting
Which statement best describes the geologic process that is most likely responsible for the formation of mountains?
They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.
They are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults
They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.
They are along a plate boundary in which plates diverged in the distance past, allowing new rock to build up.
A mid-ocean RIDGE is located at the boundary of two tectonic plates. Which diagram correctly models the relative plate motion on each side of a mid ocean ridge?
Rift valleys can from when fractures in Earth's crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?
Rift valleys from where a continental plate moves under an oceanic plate
Rift valleys form where a plate slides horizontally past another plate
Rift valleys from where two plates move away from each other.
Rift valleys form where an oceanic plate moves under another oceanic plate.
The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years.
A mid- ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America. Which statement best describes the relative motions of the Pacific and Nazca plates?
The Pacific and Nazca plates are moth moving to the east.
The Pacific and Nazca plates are both moving to the west
The Pacific plate is moving to the west, and the Nazca plate is moving to the east.
The Pacific plate is moving to the east, and the Nazca plate is moving to the west.
The image shows a plate boundary. Arrows have been added to indicate the movement of the plates.What plate boundary feature is also shown?
A ridge formed by an inactive convergent boundary
A valley forming at an active divergent boundary
A fault forming at an active transform boundary
A volcano formed by an active transform boundary
The map shows the locations of four active volcanoes in the Caribbean Sea. What do these volcanoes indicate about plate tectonics in the region?
The volcanoes form an island arc, indicating a converging plate boundary
The volcanoes form a line, indicating a diverging plate boundary.
Two plates are moving past each other, causing faulting and magma formation.
Two plates are moving apart, creating new seafloor
The diagram shows a model of the movement of two tectonic plates. When the plates collide, on plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce-
fossil layers
volcanic islands
deep-sea sediment
seafloor spreading
The model below shows two continental plates. The folded mountains in this model form at which type of plate boundary?
Transform boundary
Divergent boundary
Subduction boundary
Convergent boundary
The steepest slope on this hill can be found on the side that is facing which direction?
Which side is steeper?
The left side of the hill
The right side of the hill

What is the source of the thermal energy that heats our planet’s atmosphere?
Earth's core
Green plants
The Sun
Fossil Fuels
The Sun warms the atmosphere and drives convection currents because -
warm air is less dense, so it rises.
the warmed air cools and makes rain.
the cooler land pushes away warm air.
warm air, in contact with cool air, rotates.
Winds in our atmosphere are created as a result of which of the following processes?
Energy that is absorbed in the atmosphere
Gravitational attraction from the Moon
Density of the air particles in the atmosphere
Uneven heating of the air in the atmosphere
The major patterns of movement of air and water on Earth are the result of –
different densities of seawater and fresh water.
diversity in the height of coastal landforms.
uneven heating and the rotation of Earth.
irregular durations of daytime and nighttime.
What is one effect of the uneven heating of Earth caused by the Sun?
Rotation of Earth
Generation of wind
Oceans losing salt
Plants failing to grow
Which of the following changes would remove the source of energy that generates the convection which makes wind here on Earth?
Growing more vegetation in barren areas.
Removing all the salt from sea water.
Blocking all solar radiation.
Reversing the rotation of Earth.
Why would St. Louis have the possibility of having thunderstorms in the next 24 hours?
It is in a high-pressure area
A cold front and low pressure are approaching
It is not located near an ocean
It recently experienced a warm front
What would reduce the strength of a hurricane?
entering warmer water
traveling over the ocean
entering cooler water
If we boil water in a pot on an electric burner. How is our simulation of demonstrating convection currents different than the currents in the atmosphere and ocean?
the warm air in our model sinks instead of rises
the heat source for Earth is the sun which heats from above
the currents are all flowing in the same direction
warm water is less dense than warm air causing a difference between the models
An illustration of how a convection current creates a wind, called a sea breeze, is provided. Which of the following best explains what creates this convection current?
Salt in the ocean makes it more dense than the land, so its gravity pulls more on the air above it.
During the day, the Sun’s energy heats up the land faster, which makes the air above it warmer.
The rotation of Earth makes the air above it rotate, but not the same over land and water.
During the day, Earth’s gravity creates a high pressure area over both the land and water.
Some dye in a beaker of water is gently heated. Why are the streaks of dye seen in the water?
The hot dye is a better conductor than the cool water.
The hot dye is a better convector than the cool water.
The hot water is less dense than the cool water.
The hot water is denser than the cool water.
Which of the following correctly shows the direction of convection currents in water?
A
B
C
