Craton -CORRECTANSWER large, stable block of crust forming the nucleus of a
continent. L
Shield -CORRECTANSWER is generally a large area of exposed Precambrian
crystalline igneous and high-grade metamorphic rocks that form tectonically stable
areas. In all cases, the age of these rocks is greater than 570 million years and
sometimes dates back 2 to 3.5 billion years.
Terrane -CORRECTANSWER A fault bounded area or region with distinctive
stratigraphy
Relief -CORRECTANSWER Difference in elevation between any two points
Topographic regions -CORRECTANSWER The shape, height, and depth of the land
surface in a place or region.
Endogenic -CORRECTANSWER Forms beneath the surface
, Exogenic -CORRECTANSWER Forms above the surface
Mafic -CORRECTANSWER What kind of magma is a silicate mineral or igneous rock
that is rich in magnesium and iron, and is thus a portmanteau of magnesium and ferric.
Also has a dark color.
Felsic -CORRECTANSWER What kind of magma are igneous rocks that are relatively
rich in elements that form feldspar and quartz. A lighter color.
Viscosity -CORRECTANSWER state of being thick, sticky, and semifluid in consistency,
due to internal friction.
Effusive -CORRECTANSWER What type of volcanic eruption is usually gentle where
lava flows out steadily and slowly. Still obviously dangerous bc lava is f*cking hot
though
Explosive -CORRECTANSWER What type of volcanic eruption is a violent and
catastrophic, with pyroclastic flows and raining fragmented rocks? Think Mt. St. Helens,
Krakatoa, Pompeii - you will die in the immediate vicinity
Hot Spots -CORRECTANSWER are volcanic regions thought to be fed by underlying
