What is the boundary between two unlike air masses called? What cloud and |
Cold Fronts: Vertical clouds, Cunombilus clouds, intense but short precipitation
Warm fronts: lower clouds, attocumulus clouds/altostratus, broad but gentle rain |
|
Do hurricanes form over cold or warm water? Are hurricanes associated with moist or |
-Warm water -Moist air -They lose their power and die out. -Storm surge flooding |
|
What area of the world has the highest concentration of tornadoes, |
-US Midwest, Tornado Alley -Tornadoes have steeper pressure gradient -Higher wind speeds |
|
What two weather variables does the Koppen climate classification system use? |
-Temperature & Precipitation |
|
What rock type is formed by the cooling of magma/lava? |
-Igneous Rocks |
|
What rock type is formed by material being deposited in layers and |
-Sedimentary Rocks |
|
What rock type is formed by heat/pressure that changes the source rock’s crystal |
-Metamorphic Rocks |
|
Be able to identify on a diagram each region of Earth’s interior (mantle, inner core, |
Crust, Mantle, Outer core, Inner core |
|
At what type of plate boundary is new crust material being created? |
-Divergent is "constructive" |
|
Is a continental plate more or less dense than an oceanic plate? As a result of this |
-Ocean plates more dense, subduct/sink -Continental stays on top. |
|
What type of plate boundary is the San Andreas Fault, which runs through California? |
-Transform |
|
What process created the Hawaiian Islands? |
-Plate tectonics "Hot Spots" |
|
At what type of plate boundary is old crust subducted and recycled? |
-Convergent |
|
Which volcano type is associated with mostly explosive (pyroclastic) eruptions? |
-Cinder Cones |
|
Which volcano type is associated with mostly non-explosive (lava flow) eruptions? |
-Shield Volcanoes |
|
Which volcano type is associated with mixed eruptions of both explosive (pyroclastic) |
-Composite Volcanoes |
|
What is molten (liquid) rock called when underground – magma or lava? What is molten |
-Above: Lava -Below: Magma |
|
What is a caldera? |
a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption. |
|
What is the definition of folding? Is this considered plastic or brittle deformation? |
-When crystal rocks are stressed, lateral compression deforms by bending in folding process. -Plastic process |
|
On a diagram of a folded landscape, be able to identify a syncline, anticline, and a |
-Monocline: 1 sided fold; connects 2 levels -Syncline: Simple downfold -Anticline: Simple symmetrical upfold |
|
In relatively “young” folded landscapes does topography usually match the underlying |
- |
|
What is the definition of faulting? Is this considered plastic or brittle deformation? |
-When rock is broken with accompanying displacement (movement on 1 or both sides of break). -Usually takes place along weak crust. -Brittle deformations. |
|
Which fault type is associated with horizontal movement? What is offset drainage? |
-Stroke-slip faults -Offset drainage: Streams flowing across faults are displaced by periodic fault movement or diverted when shutter ridge is faulted in front of drainage channel. |
|
Is a normal fault associated with compressional or extensional stress? What is a scarp? |
-Extensional stress -Scarp: Steep inclined fault zone, upper block slides down fault plane normal to sense of "gravity". |
