is a naturally formed, non-living Earth material
depicts how the three major rock types - igneous, sedimentary, and metamorphic
are rocks that form from the cooling and hardening of molten magma in many different environments
are rocks that form by the compaction and cementing together of sediments, broken pieces of rock-like gravel, sand, silt, or clay
are rocks that form when the minerals in an existing rock are changed by heat or pressure below the surface
what are the key processes of the rock cycle?
crystallization, erosion and sedimentation, and metamorphism
is the formation of different mineral crystals at different temperatures as magma cools
wears rocks at the Earth's surface down into smaller pieces
what are the small fragments called?
is the depositing of sediment by wind, water, or other earth processes
layers of clearly defined different types of rock
the process of pressure morphing rock beds, which may result in repetitive layering patterns
is a vent from which the material from a magma chamber escapes
what's the difference between magma and lava?
lava is after it's been erupted out of the volcano, magma is
is a volcano found in the middle of a tectonic plate where magma rises through the mantle away from a subduction zone
what are the two types of volcanos?
effusive and explosive
Erupted rock fragments
is a geologic condition that may result in damage or risk
are depressions or holes in the ground caused by some form of collapse of the surface layer
is a sudden release of energy that shakes the ground
is a rapid flow of snow down a sloping surface
are different sizes of rock particles. Boulders are sediments; so is gravel. At the other end, silt and clay are also sediments.
is the process of movement of sediments after they have formed.
is weathering that breaks rock into smaller pieces by physical processes.
is the process of mechanical weathering in which water freezes and expands in cracks in rocks, breaking them apart.
is a form of mechanical weathering in which one rock bumps against another.
is weathering by changing the chemical composition, and also possibly size, of a rock.
is the name of the chemical reaction between a chemical compound and water
is the process of minerals or chemicals being removed from soil or rock.
is a chemical reaction that takes place when oxygen reacts with another element.
