Types of Weathering: Physical, Chemical, and Biological
The type of weathering when rocks are changed by acid such as acid rain or the carbonic acid found in wet caves.
What is chemical weathering?
The movement of sediments.
What is erosion?
The type of rock formed when molten rock (magma or lava) cools.
What are igneous rocks?
What are puzzle pieces?
The type of plate boundary where plates collide and one plate moves under another, causing the uplift of magma and the formation of most volcanoes.
What are subduction boundaries?
The type of weathering when animals burrow underground.
What is biological weathering?
The dropping of sediments.
What is deposition?
The type of rock formed by the deposition, compaction, and cementation of sediment.
What is sedimentary rock?
The 3 layers of the Earth in order from inside-out.
What are the core, mantle, and crust?
The type of plate boundary where plates collide into each other near-equally, crust is destroyed, and mountains like the Himalayas form.
What are convergent (collision) boundaries?
The type of weathering where rocks undergo oxidation and rust forms.
What is chemical weathering?
What is weathering?
The type of rock formed by extreme heat and pressure deep beneath the surface of the Earth.
What is metamorphic rock?
The name of the most recent supercontinent meaning "all land" in Greek.
What is Pangaea?
The type of plate boundary where plates move away from one another leading to magma rising, the creation of new crust, and sea floor spreading as evidenced by the Mid-Atlantic Ridge.
What are divergent boundaries?
The type of weathering when tree roots grow in the cracks of rocks, expanding and widening those cracks.
What is biological weathering?
The 3 agents of change responsible for much of the weathering and erosion on Earth.
What are wind, water, and ice?
Describes each of the main types of rocks, how they form, and how they change.
What is the rock cycle?
The circular heat transfer process taking place in the mantle that constantly moves tectonic plates.
What are convection currents?
The type of plate boundary where the plates rub, grind, or slip against one another known for earthquakes and faults.
What are transform boundaries?
The type of weathering where sediment, sand, or rocks moved by wind or water cause abrasions (scrapes) on rock.
What is physical weathering?
The remains of once living things found mostly in sedimentary rock; As new layers of sediment are deposited, the existing ones are buried deeper, meaning the bottom-most layers represent the earliest, or oldest, time periods.
What are fossils?
The process in which sediments are pressed together.
What is compaction?
This collection of data provides the strongest evidence for continental drift because it matches once-living things across continents that are now separated by oceans.
What is the fossil record?
A horseshoe-shaped zone around the Pacific Ocean known for intense seismic and volcanic activity; home to 75% of the world's active volcanoes and 90% of earthquakes due to tectonic plate interactions at subduction zones.
What is the "Ring of Fire"?
