100

The study of planet Earth, including its physical structure, its composition, its history, and the processes that act on it.

Geology

100

Croation scientist Andrija Mohorovicic was the first to make use of this data.

information gathered by seismographs

100

Any process that breaks down rocks and creates sediment.

Weathering

100

What it is called when rocks containing iron turn red.

Oxydation

100

Three types of rocks

Sedimentary, igneous, and metamorphic

200

The sum of all water on a planet is called this.

Hydrosphere

200

Mohorovicic discontinuity (or Moho for short) describes this.

The boundary between Earth's crust and the beginning of the Earth's mantle.

200

Two forms of weathering.

mechanical weathering and chemical weathering

200

Curves created when fast-moving water slams into the far side of a river.

Meanders

200

Solid, naturally-occurring, inorganic substances that have a definite chemical composition and a crystalline structure.

Minerals

300

Evaporation of water from plants.

Transpiration

300

This scientist used data from analyzing seismic waves to hypothesize the boundary between the mantle and the core of Earth.

Beno Gutenberg

300

The process that moves sediment.

Erosion

300

Two different land features formed when sediments from rivers are deposited as their flow slows entering larger bodies of water.

alluvial fans and deltas

300

Two of the four components of granite rock

Quartz, mica, potassium, and plagioclase feldspar

400

Water falling from the atmosphere as rain, snow, sleet, or hail.

Precipitation

400

This scientist's work with seismic waves led her to realize that the core actually has a solid inner region.

Inge Lehmann

400

Large boulders dropped by moving or melting glaciers

glacial erratics

400

Mineral structures found in caves formed by water dripping from the ceiling.

Stalactites and stalagmites

400

Four of the six properties of minerals

Crystal structure, color, streak, luster, hardness, and fracture/cleavage

500

Evaporation and condensation of a mixture to separate out the mixture's individual components.

Distillation

500

The border between the outer core and inner core of the Earth is called this.

The Lehmann discontinuity

500

The difference between erosion and weathering

Weathering breaks down rocks into sediment, and erosion carries the sediment away.

500

The Great Lakes are this type of lake formed by chunks of ice left behind by retreating glaciers

kettle lakes

500

A series of processes in which forces within Earth and at the surface cause rocks to continuously change from one type to another.
