Weathering, Erosion & Deposition
What process moves sediment from one place to another?
erosion
What boundary occurs when two plates slide past each other?
Transform
What natural disaster is a spinning column of air that touches the ground?
tornado
What instrument records the shaking caused by an earthquake?
seismograph
Is a delta an example of a constructive or destructive process?
Constructive
What type of weathering occurs when ice freezes in a crack and breaks rock apart?
Mechanical weathering
What boundary occurs when two tectonic plates collide?
Convergent
What natural disaster occurs when water spills over riverbanks after heavy rain?
flood
What technology uses radio waves to track storms such as hurricanes?
doppler radar
What force pulls rock, soil, and sediment downhill and contributes to landslides?
Gravity
Rust forming on rock containing iron is what type of weathering?
Chemical Weathering
What boundary occurs when two plates pull apart and magma can rise between them?
divergent
What natural disaster is usually caused by an underwater earthquake and creates a large ocean wave?
tsunami
What warning system uses ocean buoys to detect and warn people about tsunamis?
dart
Why can a volcano be both destructive AND constructive?
It can destroy existing land, but cooled lava can create new land.
What process occurs when ocean waves drop sand along a shoreline?
Deposition
What two landforms can form when tectonic plates collide at a convergent boundary?
folded mountains and volcanoes
What natural disaster is caused by a sudden release of stress in Earth’s crust?
earthquake
Name ONE structure humans can use to help protect a beach from wave erosion.
Jetties, Seawalls, Beach Nourishment, Erosion Control Mats, Sand Fences
Why would you expect many earthquakes near the Ring of Fire in addition to volcanoes?
It is located along tectonic plate boundaries where plates move/interact.
A river carries sediment downstream and eventually drops it at its mouth. Name BOTH processes occurring.
Erosion while the sediment is moving; deposition when it is dropped.
What type of plate boundary is especially associated with plates crashing together to form folded mountains?
convergent
What powerful storm forms over warm ocean water and has strong rotating winds?
hurricane
A steep hillside has experienced several landslides. Name ONE thing humans could do to help limit future landslides.
Build cement/retaining barriers
Why is a magnitude 5 earthquake much more dangerous than a magnitude 4 even though the magnitude is only one number higher?
The earthquake magnitude scale is logarithmic; a magnitude 5 releases much more energy than a magnitude 4.
