According to continental drift, the continents were once joined together as one giant landmass called Pangaea. What major forms of evidence did Alfred Wegener use to support this concept? Select TWO correct answers.

• A. The same species of bird is currently found on 2 or more continents.

• B. Similar rock and fossil evidence have been found on the coastlines of two or more continents.

• C. Magnetic striping found in seafloor spreading shows a pattern of Earth's magnetic field reversal over time.

• D. Glacier deposits have been found on two or more continents near the equator.

• E. Convection currents in the mantle move the Earth's crustal plates, causing plate boundaries to collide, separate, or slide against one another.

Which of the following represents the layers from oldest to youngest?

• Layer X→Layer Y→Layer Z

• Layer X→Layer Z→Layer Y

• Layer Y→Layer X→Layer Z

• Layer Z→Layer Y→Layer X

Which layer shows evidence that it was once a forest?

• Layer Z

• Layer Y

• Layer X

• None of the layers

Alfred Wegener discovered that the coastlines of some continents match up like a jigsaw puzzle piece. An example of this is the coastline of South America and the coastline of Africa. This information helped Alfred Wegener form the concept of

• gradualism

• glacial impact

• continental drift

• global warming

The term “seafloor spreading” is best used to describe—

• the submergence of the Pacific plate beneath the North American plate.

• the rapid drop off between the continental shelf and the abyssal plain.

• the tsunami effect associated with the eruption of underwater volcanoes.

• magma upwelling and lateral expansion along the mid-Atlantic ridge.

Which table correctly compares features of divergent plate boundaries and convergent plate boundaries?

• A. Divergent: Type of Motion - Plates move away from each other, Landforms - Ridges and rifts, Volcanic Activity - Yes; Convergent: Type of Motion - Plates move toward each other, Landforms - Trenches and mountains, Volcanic Activity - Yes.

• B. Divergent: Type of Motion - Plates move toward each other, Landforms - Ridges and rifts, Volcanic Activity - No; Convergent: Type of Motion - Plates move away from each other, Landforms - Trenches and mountains, Volcanic Activity - Yes.

• C. Divergent: Type of Motion - Plates move away from each other, Landforms - Trenches and mountains, Volcanic Activity - No; Convergent: Type of Motion - Plates move toward each other, Landforms - Ridges and rifts, Volcanic Activity - No.

Using the plate tectonics map provided, which of the following accurately explains how plate tectonics influences the Earth's surface?

• The Eurasian and North American plates moving apart at a divergent boundary form ocean basins such as the Atlantic Ocean.

• The Pacific Plate is stationary and does not contribute to the formation of volcanic islands like Hawaii.

• The interaction between the African Plate and the South American Plate at a transform boundary formed the Andes Mountains.

• The collision of the Antarctic Plate with the Australian Plate leads to the formation of hot spots beneath Antarctica.

The Pacific Plate and the North American Plate come together at the San Andreas Fault. The Pacific Plate is moving southeast while the North American Plate is slowly moving northwest. The two plates sliding against each other can cause

• a convergent boundary which will typically result in a mountain chain.

• a divergent boundary which typically results in a mid ocean ridge.

• a collision boundary which will typically result in a volcano.

• a transform boundary which will typically result in an earthquake.
