Controlling Wave and Soil Erosion
What are 2 structures people build to control water/wave damage or erosion?
Levees, jetties
What is an overflow of water onto land that is most often dry?
Flood
What is the name of the device that records the vibrations produces by the changing along fault lines?
Seismograph
The first layer of the earth is called:
Crust
I move back and forth, together and apart, I can build things up, and make things shake; what am I?
Tectonic Plates
What are structures people build to control flooding?
Dams and storm drains
Floodplain
What is the flat land that borders a river and is formed of sediment deposited by repetitive floods called?
True or False: Scientists can always predict and earthquake.
False
The only liquid layer of the earth is:
Outer Core
I move broken down sediment to new places usually by wind, water, or ice; what am I?
Erosion
What is the process of importing sand from one location and placing it in another to prevent wave erosion called?
Beach Nourishment
How are floods a constructive process?
Floods are constructive processes because they construct new land by depositing sediment in new places to create floodplains (fertile land near flood prone areas that is great for planting crops).
Two ways to prevent the damage caused by earthquakes are...
1. constructing buildings away from fault lines 2. creating buildings out of earthquake resistant materials
The largest layer of the earth is:
Mantle
I set pieces of sediment in new places; what am I?
Deposition
Farmers attempt to prevent soil erosion by adding ____________, a covering such as straw, manure, or dead leaves.
Mulch
What are 2 ways people attempt to control flooding?
dams and storm drains
DAILY DOUBLE!!! Three things scientists monitor to predict volcano eruptions?
1. Elevation and tilt caused by the movement of magma down below. 2. Gases released by the volcano. 3. Rise in temperature of underground water near volcanoes.
The deepest layer humans have traveled to is the:
Crust
I can be constructive or destructive and I come in three forms. When I wake up, I can be explosive or slow; what a I?
Volcano
Plants help prevent soil erosion because:
Their roots help hold soil into place
How are storm drains managed?
Through regular cleaning and removal of debris
Below ground molten rock is called ___________, above ground it is called ___________________.
Magma, Lava
The densest layer of the earth is the:
Core
I help scientists study earthquakes and learn about the layers of the Earth; what am I?
Seismology, seismographs, or seismic waves
