Mass Wasting

1. Mass Wasting By Miss Burke

2. Mass Wasting • What is mass wasting? • Mass means “large amount” • Wasting means “destruction” • The process that occurs when a large amount of material moves down the side of a hill, cliff, or mountain at a fast pace. • Landslides, mudslides, avalanches • What causes mass wasting? • Gravity • Changes in plant cover, overloading, and weathering • Water can speed up or slow down the process

3. Mass Wasting • How do they affect living things? • Mass wasting can cause homes of both animals and humans to be destroyed. It can also cause changes in water supply. • How can living things prevent, deal with, or change these situations? • We cannot prevent all mass wasting. The Earth’ surface will still continue to change. • We can be careful when clearing plants from an area and we can avoid building on and disturbing the land close to cliffs or mountainsides. • Other things we should know: • Mass wasting is still erosion. However, it is erosion happening very quickly.

4. Questions your group needs to answer: • What is a/an _____________? • What causes a/an __________ to occur? • How does it affect living things? • How can living things prevent, deal with, or change these situations? • Other things we should know: • This is a section where it would be important to note any connections your group made to what we have already studied.

5. Earthquakes Student Names

6. Earthquakes • What is a earthquake? • An earthquake is when the surface of the earth moves. • When does an earthquake occur? • An earthquake occurs when tectonic plates move, they rub together or slide against each other. • How do they effect living things? • When a earthquake happens electricity goes out and during a major earthquake buildings collapse and roads get destroied. People are in danger!

7. Earthquakes • How can living things prevent, deal with, or change these situations? • People cannot control earthquakes • People can build their homes to make them unlikely to fall over • Fun facts • The place where plates meet is called a fault • Most plates move at only a few centimeters a year

8. Floods By Student Names

9. Floods • What is a flood? • A flood is a big pool of destructive water that covers land and doesn't absorb. • What causes a flood? • It happens when a lake, ocean, or river overflows. • A hurricane or strong wind pushes water on the coast. • How does it effect living things? • It can destroy there homes and food resources.

10. floods • How can living things prevent ,deal with ,or change these situations? • You can build dams to stop water from coming. • Scientists built there own flood to see how to deal with floods. • People can build stuff to help know what is going to happen. • Other things we should know. • A tsunami can cause a floods.

11. Hurricanes By Student Names

12. hurricanes • What is a hurricane? • Hurricanes are huge spinning storms that develop in warm areas around the equators. • A hurricane is storm that has spiral clouds and has winds of 75 and over. • What causes a hurricane • Warm air goes up and starts to spin and the wind makes waves. • How can people deal with situations. • People can build shelters and alarm systems to warn and protect them.

13. hurricanes • How do hurricanes affect living thing s? • Hurricanes can damage roads, railroads, bridges, and airports this makes it more difficult for rescuers to reach people after the storm and in the storm. • Important facts. • Hurricanes can lead to tornados and flooding. • Sand dunes can help ocean from houses from the waves to flood the houses.

14. By : Student Names Thunderstorms

15. Thunderstorms • What causes thunderstorms to occur? • Thunderstorms are created by thunder and lightning traveling through, amongst and also clouds from the sky and ground. The most dangerous are the thunder and lightning traveling from cloud to cloud. • What are thunderstorms? • Thunderstorms are basically just clouds with lightning and thunder coming out of clouds.

16. How does a thunderstorm affect living things? • Thunderstorms affect living things by damaging their homes and injuring a lot of living things. • How can living things prevent, deal with and change these situations? • People can change these situations by putting up lightning rods.

17. Tornadoes By Student Names

18. What is a tornado? • A tornado is a is a big windstorm that destroys homes and other things • What causes a tornado to occur? • When warm air meets cold air inside a thunderstorm, the cold air sinks down and the warm air zooms up • How does it effect living things? • They destroy a lot of homes leaving people homeless • It destroys habitats and destroys animals

19. How can living things prevent, deal with, or changes these situations? • You can deal with a tornado by having a tornado safety kit. • You can cover your head with your arms to protect your body and head. • You can not prevent a tornado. • Other things you should know. • A tornado gets bigger by getting more bigger by air in.

20. Tsunamis By Student Names

21. Tsunami • What is a Tsunamis? • A tsunamis is a giant destructive wave from the ocean. • What causes a tsunami? • A tsunami happens when giant chunks of the ocean floor move as a result of a earthquake.

22. Tsunami • How do they affect living things? • If you live on a beach and a Tsunami comes it will not be safe. • How can YOU deal with a tsunami? • You can plant trees to help protect you're village/ town. (You can NOT stop tsunamis .) • Other things you should know. • Big tsunamis are like huge walls of water. They can be very big.

23. Volcanic Eruption By Student Names

24. What is volcanic eruption? • Volcanic Eruption is the build-up of pressure in the magma camber below the volcano is often the main trigger for an eruption • What causes a volcanic eruption ? • When more and more magma fills the magma chamber, pressure causes the ground to bulge until it puts so much pressure that the volcano erupts • If the magma pushes its way completely out of the ridges undersea volcanos erupt

25. How does it effect living things? • Lava can burn houses, destroy villages and bury everything in its path • The heat comes from a volcanic eruption can melt the snow or ice that may be on the volcano which would flood nearby inhabitants • Ash from a volcano can suffocate people in the area

26. How can living things prevent, deal with, or change these situations? • scientists study volcanos so they know when one is going to erupt for example when a bulge forms that means the volcano will erupt • Other things you should know. • during an eruption you might see lightning which is likely caused by the mixture of ash gases and ice

27. Wildfires By Student Names

28. Wildfires • what are wildfires? • Wildfires are fires that go out of control • They are mostly in forests • How are they caused? • they are mostly caused by regular events • Wildfires are sometimes caused by people

29. Wildfires • How does it affect living things? • Most animals and people flee • They mostly do it before it gets big • How can living things prevent, deal with, or change these situations? • They deal with it by cutting down dead trees so there not fire fuel

30. Wildfires • Other things we should know • The average forest fires in the U.S. is 100,000 • The average speed of a wildfire is 12 mi. per hour
