arch (sea arch) – Bridge of rock left above an opening eroded in a headland by waves. (Begin Chapter 14)
anthropogenic greenhouse gasses – made by humans
hot spring – A spring that emits water ranging in temperature from about 30 ¡C to 104 ¡C
Porphyritic (igneous rocks) – big and little crystals (mixture)
Brachiosaurus – tallest dinosaur; could lift head above shoulders, saurapod
The Prudhoe Bay Sadlerochit Sandstone is an example of a buried pt sandstone (T/F) – False
Silicates – chemical compound that makes up Evaporites: SiO2 (Quartz)
Cinder Cone – pyroclastic material builds up to cone
Mesosphere – Lower sphere. Rigid layer
Aridsols – white/calcium/grass and brush
Fast movements – Rock & Avalanche – (Rock Fall)
oceanic crust – earths crust located under the ocean; made of basalt
erosion – movement, floods, wind, rocks fall
What's the theory of plate tectonics – Plates move and "build" geologic features. Convection drives the plates
sedimentary rocks that are made from things once living are called – organic
Aridsols – white/calcium/grass and brush
sedimentary rocks that are made from things once living are called – organic
Surface Waves – Complex waves that move the ground in two different directions at the same time.
Cinder Cone – Medium viscosity, medium volatiles, small volumes, fall deposits built around eruptive vent
mafic – Igneous Rock containing large amounts of Iron and Magnesium, dark in color
