Volcanoes
An opening in the Earth's crust that releases ash, gases, steam, and hot liquid rock called magma
What is an earthquake?
An earthquake is a sudden shaking of the ground. Earthquakes happen every day but most are too small to notice.
What is a landslide?
A landslide is when a large amount or earth, rock, mud, and other material moves down a slope
What is weathering?
Weathering is when rocks are broken down into small pieces.
What is erosion?
Erosion is when small pieces of rock are moved away
Gas bubbles inside magma cause pressure to build up. The pressure builds until there is an eruption.
What causes an earthquake?
Earth's plates are constantly moving. When the plates scrape, bump into, or push and slip past another plate an earthquake happens.
What causes a landslide?
Landslides can be caused by earthquakes, volcanic eruptions, floods, heavy rain, melted snow, weathering, and erosion.
What causes weathering?
Weathering is caused by water, temperature changes (freezing water in rock), wind, plants (roots growing in rocks and breaking it), and glaciers (large blocks of ice).
What causes erosion?
Erosion can be caused by water from a river or ocean waves carrying away the small pieces of rock. Glaciers can also carry away pieces of rock as they slide down a mountain, making a U-shaped valley. Wind can also blow and carry away small pieces of rock.
Lava can burn, bury, or damage thing. When lava erupts from the earth's surface, the lava hardens and can form mountains and islands.
What are the effects of an earthquake?
Earthquakes can cause landslides, tsunamis, flooding, windows to break, buildings to collapse, and fires.
What are the effects of a landslide?
Landslides can destroy trees, roads, bridges, cars, homes, and harm people.
What are the effects of weathering
After rock is weathered, erosion can happen.
What are the effects of erosion?
Erosion changes the land by carving out valleys, canyons, changing rocks from plateaus to spires, and making beaches smaller. Erosion can also lead to landslides.
Can eruptions be prevented?
No, eruptions cannot be prevented, but scientists can predict when an eruption will happen so less people are harmed.
Can earthquakes be prevented?
Earthquakes cannot be prevented and cannot be predicted, but engineers are working to build earthquake-proof buildings.
Can landslides be prevented?
Engineers can help to prevent landslides by building water pipes to keep water away from the soil on a slope. Building retaining walls can prevent some of the damage done by landslides. Also, the land can be covered to keep away water.
Can weathering be prevented?
Weathering can be prevented by planting vegetation. It can also be prevented by building windbreaks to stop the wind, dikes and dams to capture water, and retaining walls to stop water from reaching the rock.
