What is?
Rock that behaves like something between a liquid and a solid
What is Plastic Rock?
Scientists know much about the Earth's interior because they observe this wave type
What are Seismic Waves?
The magnetic field of the Earth is generated here
What is the core?
In the hydrologic cycle, these two processes bring water up into the atmosphere from Earth's surface
What are evaporation and transpiration?
The lithosphere, the asthenosphere, and the mesosphere.
What are the layers of the Earth's mantle?
The sum of all water on a planet
What is Hydrosphere?
The 4 layers of the Earth are
What is inner core, crust, outer core, and mantle?
This is not a major rock classification
What is plastic rock?
One part of a very large rock is sheltered by a cliff overhang. The other part of the rock is exposed to the elements. The exposed rock area is covered with lots of holes and depressions. What type of weathering is this?
What is chemical weathering?
3 land features caused by glaciers
What are cirques, horns, U-shaped valleys, ridges, glacial lakes, erratics, till, kettle lakes.
Small, solid fragments of rock-like gravel, sand, silt, mud, or clay
What is Sediment?
The layer between Earth's crust and mantle
What is the Moho discontinuity?
This is formed when existing sedimentary or igneous rocks change because of extreme pressure and temperature.
What is metamorphic rock?
The difference between weathering and erosion.
What is Weathering breaks down rocks into sediment, and erosion carries the sediment away?
What are Earth's crust and mantle?
Solid, naturally occurring, inorganic substances that have a definite chemical composition and a crystalline structure.
What are Minerals?
Plastic rock can do this when it experiences abrupt force.
What is harden into a firm solid?
The majority of the Earth's water supply is contained here
What are oceans?
Sand dunes are formed by wind erosion and the resulting deposition of sand. This type of weathering is known as
What is mechanical weathering?
The Gutenberg discontinuity is between these two layers.
What is the mantle and outer core?
Evaporation of water from plants
What is Transpiration?
The inner core is solid even though it has a higher temperature than the outer core.
What is extreme pressure of the inner core?
The largest source of liquid fresh water on Earth.
What is groundwater?
Four of the six properties of minerals
Crystal structure, color, streak, luster, hardness, and fracture/cleavage
True or False: Alluvial fans are formed by glaciers?
What is False?
