Unit 7 - Plate Tectonics 1st period

What type of boundary is shown in the diagram and why can you classify it that way?

• A divergent boundary because the tectonic plates are moving apart from each other

• A convergent boundary because the tectonic plates are moving toward each other

• A convergent boundary because the tectonic plates are moving side to side

• A divergent boundary because the tectonic plates are moving toward each other

Scientists have discovered fossils of Lystrosaurus, a plant-eating dinosaur, in Antarctica, India, and South Africa. Based on this discovery, which of the following conclusions could scientists most likely make about how Earth has changed over time?

• Ancient reptiles and plants were able to survive in extremely cold temperatures and have only recently evolved to live in warmer climates.

• Antarctica was once located at the equator.

• Antarctica was located closer to other continents and had a warmer climate better suited for plant and reptilian life.

• At some point in geologic history, the poles were warm and the equator was extremely cold.

Scientists predict that in approximately 10 million years, the African continent will split into two separate landmasses, creating a new ocean basin between them. Which of the following statements is the best evidence that supports this idea?

• There are volcanoes, such as Mt. Kilimanjaro, near the eastern coastline of Africa.

• Scientists predict that in approximately 10 million years, the African continent will split into two separate landmasses, creating a new ocean basin between them. Which of the following statements is the best evidence that supports this idea?

• There are mid-ocean ridges forming along the eastern portion of the continent.

• There is an ocean trench forming along the eastern portion of the continent.

A class is analyzing five layers of rocks. They list the fossils found in each layer.

Layer M: Plants, Dinosaur

Layer N: Trilobites, Ammonites

Layer O: Ammonites, Shelled organisms

Layer P: Mammals, Plants, Dinosaurs

Layer Q: Mammals, Plants

The class researches to discover the following four facts.

1.    Trilobites and ammonites are some of the oldest fossils found in these rock layers.

2.    Trilobites went extinct before ammonites.

3.    Fossil evidence indicates mammals evolved around the same time that dinosaurs went extinct.

4.    Fossil evidence of shelled organisms indicates they evolved before plants and dinosaurs.

Which option provides the most likely natural position of the rock layers, from deepest to most shallow, based on the law of superposition?

• Q, P, M, N, O

• N, O, M, P, Q

• N, M, P, Q, O

• O, P, Q, M, N

How can super volcanoes be distinguished from other volcanoes?

• They are very large and erupt very frequently.

• They only form at hot spots and erupt very frequently.

• They are very large and have extremely large eruptions.

• They only form in the ocean and have extremely large eruptions.

The Hawaiian Islands and Yellowstone supervolcano were both formed over fixed locations in the mantle where the magma is much hotter than in surrounding areas. The Hawaiian Islands are in the middle of the Pacific Plate. The Yellowstone supervolcano is located on the North American Plate. Which statement below correctly identifies a similarity shared by these volcanoes?

• They are both located near subduction zones

• They are both located over hot spots

• They both formed at convergent plate boundaries

• They both formed from oceanic crust

Movement at plate boundaries results in different geologic features, which can be used to distinguish one type of boundary from another. Mountain-building on Earth’s surface generally occurs at                         , while ocean basin formation occurs at                           .

Which terms, in order of appearance, best complete the sentence?

• convergent boundaries; divergent boundaries

• divergent boundaries; convergent boundaries

• divergent boundaries; transform boundaries

• convergent boundaries; transform boundaries

Earthquakes occur along                                           lines and cause a large amount of                                     to be released. This creates                                               waves, which cause the ground to shake.

Which terms, in order of appearance, best complete the sentences?

• fault; matter; light

• fault; energy; seismic

• divergent; matter; seismic

• convergent; pressure; energy

• moved laterally (sideways); transform

• moved apart; transform

• moved apart; divergent

• moved together; convergent

Which of the following statements supports the claim that the continents were not always where they are now?

• Exposed rock formations in West Texas have rock layering that is similar to formations in New Mexico.

• Lycophytes are a now extinct tree-like plant whose fossil remains have been found in Oklahoma.

• Fossils of dinosaurs have been found in Asia.

• The eastern coastline of South America appears to closely match the western coastline of Africa.
