1. What are some of the volcanoes in America that are active? Name three.
2. Write two of the results o earthquakes.
Answer in complete statement.
1. The volcanoes that are active:
Mount St. Helens (USA, Washington State)
Popocatépetl (Mexico), Volcán Villarrica (Chile)
2. Two results o earthquake: Structural Damage, Tsunamis
Type of plate movement causes the formation of fold mountains.
Convergent boundaries, where two tectonic plates collide, such as the Himalayas.
Large Mountain ranges form_______.
when rocks get folded or pushed up where plates converge.
What is the name of the plate boundary that slides past each other? Image 2
As plates push together, one plate is forces under the other. As the bottom plate starts to melt, magma rises and forms volcanoes at the surface. im5
3. What are some other processes, besides plate motion, that make major changes to Earth’s surface?
Erosion, weathering, volcanic activity, glaciation, sedimentation.
Type of force causes the formation of fault-block mountains.
Tensional forces, where the Earth’s crust is pulled apart.
This piece of equipment can measure the magnitude of an earthquake.
Seismograph
Which of these events can ONLY happen on a divergent boundary? image 3
How did the Hawaiian Islands form?
4. What are the two types of weathering?
The breakdown of rocks into smaller particles through physical, chemical, or biological means. This process contributes to the formation of soil and changes the shape of mountains and rocks.
How volcanoes shape Earth’s surface?
By erupting lava, which hardens into new landforms.
Which type of plate boundary would cause mountains to form. image 1
Where is the point on the Earth’s surface directly above the focus of an earthquake?
Type of features formed by wind. Just two are correct.
sand suns, loess
arches, scoured and blasted rocks.
5. What is a glacier?
Is a massive, slow-moving body of ice that forms when snow accumulates over time, compresses, and turns into ice. Glaciers are powerful agents of erosion and play a significant role in Earth's water cycle.
What causes earthquakes?
Sudden release of energy along faults or fractures in the Earth’s crust due to tectonic plate movement.
Transform boundaries are most likely to produce what phenomenon?
What is molten rock that has formed deep within the Earth?
What process most likely formed the Grand Canyon?
erosion by a river (water)
TRUE OR ALSE
