Core (Outer and Inner)
Made of? |
|
Definition
Innermost zone of earth. There's a solid core on the inside and a liquid core on the outer edge.
An iron/nickel mixture. |
|
|
Term
Mantle.
Made of? What's upper surface like?
What's the ASTHENOSPHERE? |
|
Definition
The zone surrounding the core.
Made of mostly solid rock.
The upper surface is soft and partially melted (ATHSENOPHERE) Can be moved around.
Out layer is crispy again. |
|
|
Term
Crust. Made of?
Lithosphere. |
|
Definition
Uppermost layer of earth. Made of rock: QUARTZ (sio2)
Lithosphere is the crust and the rigid upper part of the mantle. |
|
|
Term
| Convection Cells. Where do they come from? What does it cause? |
|
Definition
| Are heat currents in the ASTHENOSPHERE. The heat comes from core activities. The heat causes plates to move! |
|
|
Term
| Divergent Plate Boundaries. What happens? Associated with? |
|
Definition
| MOVE APART FROM EACH OTHER. Magma comes up and fills in land. Associated with SEAFLOOR. |
|
|
Term
|
Definition
Divergent, in the ATLANTIC ocean. Part of the longest mountain range in the world.
Separates:
Eurasian Plate and North American Plate African Plate from the South American Plate. |
|
|
Term
| Convergent Boundaries. Two types? What do they do? Create? Associated with? |
|
Definition
Colliding together.
SUBDUCTION: Oceanic goes under land and melts, magma spews to surface.
TRENCHES (ocean plate down), MOUNTAIN CHAINS (plate collision) VOLCANOES (increased magma)
CONTINENTAL COLLISION: Two land colliding together, crunch together and form mountains. |
|
|
Term
| Transform Boundaries. Causes? Effects? Examples? |
|
Definition
| Sliding by each other. Earthquakes come from catches and releases, not very strong. Example: San Andreas fault, California. |
|
|
Term
| Earthquake Strength Rules... Compression? Rock squeezing and slipping? Deep earthquakes are from...? |
|
Definition
Deep and Strong: COMPRESSION.
Rock stores energy when SQUEEZED. Stretched rock BREAKS, no potential energy. |
|
|
Term
Viscosity? What is it?
High in Silica = ?
Low = ? |
|
Definition
It's the thickness of magma, indicates how much silica there is.
High in silica means THICK
Low means RUNNY |
|
|
Term
|
Definition
| Fast-moving current of superheated gas and rock. Super fast terrorist lava. |
|
|
Term
|
Definition
| mMdflow or debris flow composed of a slurry of pyroclastic material, rocky debris, and water. |
|
|
Term
|
Definition
| is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. AROUND EDGES OF ALL THE CONTINENTS IN THE CENTER OF THE MAP. |
|
|
Term
|
Definition
| Huge damn volcano. The Krakatoa volcanoes erupted and exploded in 1883. Loudest sound ever~ |
|
|
Term
|
Definition
| Huge ass waves caused by displacement of land, usually by earthquakes! |
|
|
Term
|
Definition
| Solid combos of one or more minerals (limestone is mineral with icon, granite is three combined: mica, feldspar, and quartz!) |
|
|
Term
|
Definition
| A natural element or inorgranic compound, soldid and regular looking crystal structure. |
|
|
Term
| ORE!?!? High and low grade. |
|
Definition
| Rock that has enough mineral to mine. High grade = high amounts of mineral. Low Grade = lower amts. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Rock from erosion particles, often in the water! |
|
|
Term
|
Definition
| "change in form" rock, from heat and pressure. |
|
|
Term
|
Definition
| NOT EROSION. breaking down of rocks, soils and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and waters. |
