Earthquakes
These are the waves that are created by earthquakes and are measured by scientists
Seismic Waves
What magma is called when it's above ground
Lava
These slow processes change the landscape of our Earth
Weathering, erosion and deposition
Sand being moved by wind
Erosion
This is what drives the processes of weathering, erosion and deposition
The Sun
This can occur following a major earthquake and release additional energy
Aftershock
Fast, extremely hot clouds of gas and ash that destroy everything in their path
Pyroclastic Flow
These are the two branches, or types, of weathering
Mechanical and Chemical
Ocean waves pounding against a rocky cliff and wearing it down
Weathering
Occurs when water seeps into cracks, freezes and expands, breaking rock apart
Ice or Frost Wedging
These seismic waves arrive first on a seismograph and are usually the smallest in amplitude?
P waves, AKA primary waves
3 Hazards that result from a volcanic eruption
Lahar, liquefaction, tsunami, earthquakes, mudflow
Acid rain breaking down a statue and smoothing it out over many of years
Chemical weathering
A river forming a canyon by carrying away weathered rock and soil over millions of years
Erosion
The scale used for measuring the magnitude of Earthquakes
Richter scale
On Earth's surface, directly above the focus
Epicenter
The term for a liquids resistance to flow. The higher resistance, the thicker it is and slower moving it is.
Viscosity
A hurricane moves thousands of tons of sand from the bottom of the ocean to form a new beach
Deposition
A landform of sediment deposited where a river flows into an ocean
Delta
One of the types of lava flow names, originated from Hawaii
Aha (rough) or Pahoehoe (smooth)
Where an earthquake originates (begin) underground
Focus
This volcanic feature is formed when a volcano collapses after a huge eruption.
Caldera
A deposit of sediment formed where a stream leaves a mountain range
Alluvial Fan
A mass of sediment carried down and deposited by a glacier
Moraine
The four methods of erosion
Wind, water, ice and gravity
