Use your Plate Boundaries Foldable to answer this question. Which event can the students best demonstrate with their model?

Answer explanation

When tectonic plates slide against each other at transform boundaries, pressure builds up until the plates suddenly slip. This sudden release of pressure causes an earthquake.

The image shows mountain ranges in the United States. Which of the following forces caused these mountain ranges to form?

• glacial drift

• volcanic eruption

• physical weathering

• crustal plate movement

Answer explanation

Convergent Plate Boundaries: At these boundaries, tectonic plates move toward each other. When plates of continental crust come together, they can push up the land over time. This can create large mountain chains, such as the Himalayas.

A team of geologists travel to a different volcano to film an eruption for a show called Volcano Hunters. The team would most likely find an active volcano where two tectonics plates do what? Type one of the following answers: Meet, Are long the equator, Near the Poles or Where the crust is the thickest.

(a)  

Answer explanation

When plates of oceanic crust come together, they can create a subduction zone. A subduction zone is a convergent boundary where the denser of the two plates is pushed beneath the other. Eventually, the denser plate is pushed far enough into the mantle that it begins to melt. Subduction zones also form where oceanic crust collides with continental crust. Because oceanic crust is denser, it is always subducted beneath continental crust at a subduction zone. Volcanoes are common around subduction zones as crust melts into magma. Subduction zones also create the deep ocean trenches where oceanic crust is destroyed.

Draw the profile (side view) of this topographic map.

Answer explanation

The peak is towards the Left/West side. The Left/West side of this topographic map has lines that are very close together that make it a steep slope. The Right/East side of this map has lines that are far a part that make it a gradual/flat slope. You can see how the peak is 2000m in elevation and taller than the outside ring of 1800m in elevation.

Which profile most likely represents the landscape today?

• 
• 
• 
• 

Answer explanation

The peak has eroded 7 m. You need to subtract. 217m - 7m = 207m which is the elevation of the peak currently.. The elevation of the peak has changed but the shape of the landform has the same overall shape. The Left/West side of the landform is steep since the lines are close together and the Right/East side of the landform has wide/far a part lines which make this side have a gradual/flat slope.

Captured on June 27, 2009, this true-color image shows part of the White Sands National Monument in New Mexico, where brilliant white gypsum dunes slowly migrate toward the northeast. Which of these most likely caused the changes in the dunes?

• Ocean Waves

• Flowing Rivers

• Blowing Wind

• Crust Uplift

Answer explanation

The agent erosion of blowing wind causes the formation and changes of sand dunes.

What is the elevation at point X in the image provided? Type in the exact number with no units.

(a)  

Answer explanation

• Cattle that eat grass and feed

• Goats that eat weeds and shrubs

• Turkeys that eat seeds and fruit

• Hogs that eat, fruit, seeds, and feed

Answer explanation

White-Tailed Deer's diet is mainly shrubs and vines. Goats that also eat shrubs will lose some of their food source since the White-Tailed Deer compete the most for shrubs than the other types of food on the pie chart.

What is the contour interval of this map? Type in the exact number with no units.

(a)  

Answer explanation

1.) Find any two labeled points and subtract them. NO NEGATIVE NUMBERS. 1200 - 1120 = 80. THIS IS NOT THE CONTOUR INTERVAL AND ONLY THE ELEVATION BETWEEN THESE TWO POINTS. 2.) Divide the elevation you got, 80, by the number of spaces between the two. 80 / 4 = 20. YOUR CONTOUR INTERVAL IS 20 (METERS). This means as you go up and down the mountain, it goes by 20 m each contour line.

Use the contour interval to find the elevation in meters at point X. HINT: POINT X IS BELOW 1080. Type in your answer with no units.

(a)  

Answer explanation

Labeled Elevation 1080 - 20 (Contour Interval 1 Space) = 1060m
