Plate Tectonics

Front

What evidence does Stacey look for to determine whether the valleys were formed by glaciers? Options: valleys with lots of trees on either side, valleys with lots of fossils in the rock layers, valleys that are V-shaped, valleys that are U-shaped.

Back

valleys that are U-shaped because when the glaciers slowly moved through the area they scraped away and smoothed the rock

Front

Which observations about the Rocky Mountains and the Appalachian Mountains would support the claim that exposure to weathering and erosion over time can change landforms? Options: The Appalachian Mountains are found in the eastern United States and the Rocky Mountains are found nearer the west coast., The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains., The length of the Appalachian chain is approximately 2,400 kilometers and the Rocky Mountains chain is about twice as long., The Appalachian Mountains are composed mostly of sedimentary rocks while the Rocky Mountains also contain other rock types.

Back

The shorter and more rounded Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains.

According to the theory of plate tectonics, what process occurs at a transform boundary?

Back

________________________ also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth’s volcanoes and earthquakes take place along this area. This place is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean.

What type of fault is depicted in the diagram? A type of fault where the hanging wall slides downward; caused by tension in the crust

Back

normal fault

Front

At a reverse fault plates are being pressed together creating what kind of stress? A reverse fault is a type of fault where the hanging wall slides upward; caused by compression in the crust.

Back

compression
