Earthquakes
in geology, a large fragment of Earth's crust and upper mantle
Plate
Ways people have prepared themselves for a tsunami
Seawalls, warning systems, building more inland, etc.
Difference between magma and lava
magma- molten rock below Earth's surface
lava- molten rock from Earth's mantle that has reached Earth's surface
small pieces of rock or hard material that has broken down over time
sediment
definition of mass movement...
downhill movement of a mass of earth surface material
The cause of an earthquake
Plate movement
The physical cause of a tsunami
Plate movement/earthquake/water displacement
A mountain on the ocean floor made from volcanic activity
seamount
process of breaking rock into smaller pieces
weathering
plant vegetation, build retaining walls or terraces, pillar anchors, etc.
A tool used to detect and measure an earthquake's magnitude
Seismometer
tsunami definition...
a wave or series of waves caused by displaced water
Name 2/3 tools scientists use to predict when a volcano is likely to erupt
tiltmeter, spectrometer, seismometer
A procedure of study used to examine and measure features of areas of land
survey
definition of landslide...
a form of mass movement in which a large section of a slope slides downhill all at once
The size or extent of an earthquake
An example of a NATURAL barrier that can reduce the impact of a tsunami
Spongey soil, wetlands/mangrove forests
hot spot definition...
a plume of magma that causes eruptions through Earth's crust without plates interacting
definition of creep...
a word used to refer to the slow process of erosion
Evidence of future landslides
new boulders at the base of a slope, tilting trees or poles, exposed roots, etc.
The 4 layers of the Earth
Inner core, outer core, mantle, crust
A tool used to detect/send warnings of a tsunami
tsunameter
Describe a dormant, active, and extinct volcano
dormant- hasn't erupted in a while, but could erupt again
active- has erupted recently and is likely to erupt again
extinct- has not erupted in a long time and is unlikely to erupt again
Causes/agents of erosion
water, wind, animals/humans, etc.
Causes of landslides
earthquakes, volcanic activity, gravity, drought/fires that wipe out vegetation, etc.
