Classifying Rocks

NAME _________________________________
Across
When sediments are deposited, or dropped off, in a different location. These processes change the way the surface of the earth looks over time.
The breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity.
Melted or molten rock material beneath Earth's surface; cools slowly to form rocks with large crystals.
Changing variables due to the weight of overlying rocks, causing changes to rock characteristics and mineral composition, thus forming metamorphic rocks.
The unique combination of solid elements and compounds that make up a mineral.
Is formed when lava or magma cools and solidifies. Lava cools quickly and forms rocks with small crystals, while magma cools more slowly and forms rocks with larger crystals.
Process by which soil and rock particles are worn away and moved elsewhere by gravity, or by a moving transport agent-wind, water or ice.
Down
Molten rock or magma that has reached Earth's surface by volcanic action; characterized by small crystals due to rapid cooling on Earth's surface.
Occurs when compacted sediments stick together and turn into rock.
Forms when particles of other rocks are deposited into layers and are compacted (crushed together), and cemented (binding of the sediments).
Occurs when rock particles or sediments are pressed together or packed down by gravity and the pressure of overlying rock layers.
Metamorphic rock is formed deep underground where heat and pressure cause existing rocks to be changed in both mineral composition and structural characteristic.
Earth's rocks change from one type into another over time due to various Earth processes. Changes occur in mineral compositions and physical structures.
