- 1State 4 events that can change earth's surface quickly.volcanoes, earthquakes, landslides, floods
- 2Describe how volcanoes can change earth's surface quicklyVolcanoes create mountains by bringing new rock material to
the surface. Volcanoes also throw out lots of rocks and ash, which
fall to Earth. These earth materials form a new earth surface. - 3Describe how earthquakes can change earth's surface quicklyThe shaking of the ground can cause rock to rise or drop and trigger landslides if the ground is unstable. As a result, mountains and cliffs
build up, and rock materials can move downward to different locations. - 4Describe how floods can change earth's surface quicklyFloods move large amounts of earth materials (rock and soil) from one
place to another. Floods in rivers may create new meanders, sandbars,
and so forth when the eroded materials are deposited. - 5Describe how landslides can change earth's surface quicklyRock material moves from high locations to low locations during slides, eroding earth material from the top and depositing it
at the bottom. - 6What are the layers of earth?Inner core, Outer core, Mantle and Crust
- 7What is magma?Melted rock inside Earth’s interior.
- 8What is Lava?Melted rock after it escapes Earth’s interior
- 9What are some signs that a volcano might become active?bubbling soil, hot springs
- 10What layer of earth do we live on?crust
- 11How do active volcanoes change earth and what can the lava be used for?builds new land, creates fertile soils, paves roads, can be used for energy
- 12What are tiltmeters and what are they used for?Measures the swelling of the ground
