The highest mountain in the world is? | Mt. Everest |
What is the difference between elevation and actual height? | Elevation-is feet above average or mean sea level Actual height-height of a mountains summit above lowest elevation |
Which Mountain has the highest elevation in the U.S | asia |
Where can mountains be located? | mountain range/system |
which is the longest and most extensive mountain range on earth | mid-atlantic ridge |
Buttes, pinnacles, and fins are all thought to be erosional remnants of? | mountains |
what are the primary causes of most depositional hills and mountains | wind, glaciers, volcanoes |
what types of mountains are most commonly associated with volcanoes? | depositional, tectonic |
Is Mt. Everest growing? | yes |
Where are tectonic mountains formed? | in between two plates colliding |
What are rift valleys and where are they usually located? | a series of steep-walled valleys lined with high cliffs |
What are stone arches and how were they formed? | section of rock weakened at the base of a fin, and some of fin collapsed |
Describe some of the unique geologic features of the western United States from a biblical perspective | Mountainy, rigid, mines, winters |
What type of rock are volcanoes made out of? | igneous |
Most common structure for volcanoes | strata volcano |
Activity levels of volcanoes and what they mean | active-currently erupting, dormat-an inactive but uneroded volcano, extinct-no activity |
Which volcano is in Washington State? | Mt. Saint Helens |
What the VEI is based on? | explosive power in eruption |
What is the difference in direction of dikes and sills? | sills-horizontal, dikes-vertical |
What is a hydrothermal circuit and where is it best seen? | geothermal flow of water, volcanoes |
What does a pyroclastic flow contain? | gases |
Where is the Ring of Fire? | pacific ocean |
Have volcanoes that were considered dormant ever erupted? | no |
How is geyser water heated? | igneous intrusion heats the long, twisted chamber of water |
How did the eruption of Mt. Tambora affect the earth? | Long winters, famine, starvation |
Why are there not a lot more geothermal energy plants in the United States? | its expensive and the drilling requires hard work |
a ridge-shaped fold of stratified rock in which the strata slope downward from the crest. | Anticline |
a process in which a section of the earth's crust is folded and deformed by lateral compression to form a mountain range. | orogeny |
a wide, round open container, esp. one used for holding liquid. | Basin |
an isolated hill with steep sides and a flat top (similar to but narrower than a mesa | butte |
a rounded vault forming the roof of a building or structure, typically with a circular base. | Dome |
unsorted material deposited directly by glacial ice and showing no stratification | till |
an isolated flat-topped hill with steep sides, found in landscapes with horizontal strata. | Mesa |
a line of mountains connected by high ground | Mountain range |
a bend in rock strata that are otherwise uniformly dipping or horizontal | Monocline |
an elongated block of the earth's crust lying between two faults and displaced downward relative to the blocks on either side, as in a rift valley. | grabens |
A Mountain range or mountain belt is a geographic area containing numerous geologically related mountains | Mountain system |
mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity. | Moraine |
an area of relatively level high ground. | plateau |
a submarine mountain. | Seamount |
the equilibrium that exists between parts of the earth's crust, which behaves as if it consists of blocks floating on the underlying mantle, rising if material is removed and sinking if material is deposited. | isostacy |
a trough or fold of stratified rock in which the strata slope upward from the axis. | Syncline |
The variations in elevation of an area of the earth's surface | relief |
a broad, domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava. | shield volcano |
A flood basalt or trap basalt is the result of a giant volcanic eruption or series of eruptions that coats large stretches of land or the ocean floor with basalt lava. | flood basalts |
a large volcanic crater, typically one formed by a major eruption leading to the collapse of the mouth of the volcano. | caldera |
a volcano built up of alternate layers of lava and ash. | stratovolcano |
energy derived from the heat in the interior of the earth | geothermal energy |
a small piece of partly burned coal or wood that has stopped giving off flames but still has combustible matter in it. | cinder |
n opening that allows air, gas, or liquid to pass out of or into a confined space. | vent |
rock fragments and particles ejected by a volcanic eruption. | tephra |
a cone formed around a volcanic vent by fragments of lava thrown out during eruptions. | cindercone |
lava that has solidified as rounded masses, characteristic of eruption under water. | Pillow lava |
mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust. | volcano |
large, bowl-shaped cavity in the ground.caused by an explosion or the impact of a meteorite or other celestial body. | crater |
a destructive mudflow on the slopes of a volcano. | lahar |
an opening in or near a volcano, through which hot sulfurous gases emerge. | fumarole |
a gas-fired water heater through which water flows as it is rapidly heated. | geyser |
hot molten or semifluid rock erupted from a volcano or fissure, or solid rock resulting from cooling of this. | lava |
the powdery residue left after the burning of a substance. | Ash |
Hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed by cooling. | magma |
