Chapter 18 Vocab

Section 1-3

TermDefinition
Volcanism Describes all the processes associate with the discharge of magma, hot water, and steam.
Hot Spots Unusually hot area in Earth's mantle where high-temperature plumes of mantle material rise toward the surface.
Flood Basalts Huge amounts of lava that erupt form fissures.
Fissures Are long cracks in Earth
Conduit A tube like structure that allows lava to reach the surface.
Vent Opening in Earth's crust through which lava erupts and flows out-onto the surface.
Crater Continental core formed from Archean or Proterozoic micro-continents; deepest (as far as 200 km into the mantle) and most stable part of a continent.
Calderas Large crater, up to 50 km in diameter, that can form when the summit or side of a volcano collapses into the magma chamber during or after an eruption.
Shield Volcano Broad volcano with gently sloping sides built by nonexplosive eruptions of basaltic lava that accumulates in layers.
Cinder Cones Steep-sided, generally small volcano that is built by the accumulation of tephra around the vent.
Composite Volcanoes Generally cone-shaped with concave slopes; built by violent eruptions of volcanic fragments and lava that accumulate in alternating layers.
Viscosity A substance's internal resistance to flow.
Tephra Rock fragments, classified by size,l that are thrown into the air during a volcanic eruption and fail to the ground.
Pyroclastic Flows Swift-moving, potentially deadly clouds of gas, ash, and other volcanic material produced by a violent eruption.
Plutons Intrusive igneous rock body, including batholith, stocks, sills, and dikes, formed through mountain-building processes and oceanic-oceanic collisions; can be exposed at Earths's surface due to uplift and erosion.
Batholiths Coarse-grained, irregularly shaped, igneous rock mass that covers at least 100 km2, generally forms 10-30 km below Earth's surface, and is common in the interior of major mountain chains.
Stocks Irregularly shaped Pluton that is similar to a batholith but smaller, generally forms 5-30 km beneath Earth's surface, and cuts across older rocks.
Laccolith Relatively small, mushroom-shaped Pluton that forms when magma intrudes into parallel rock layers close to Earth's surface.
Sill Pluton that forms when magma intrudes parallel rock layers.
Dike Pluton that cuts across preexisting rocks and often forms when magma invades cracks in surrounding rock bodies.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
