| Question | Answer |
|---|---|
| Describe the relief of: A. The Himalaya Mountains B. The Great Plains in the Midwest United States | a. Have high relief B. Have low relief |
| Where is the most extensive mountain system inn the world located | Mid Atlantic Ridge |
| How are the tectonic mountains created? | Tectonic mountains are created when TECTONIC plates COLLIDE, PULL apart, LIFT up, or SUBSIDE |
| Where are most rift valleys located? Give an example of an exception | Most rift valley structures are located at mid - ocean RIDGES between DIVERGING oceanic plates. One major exception to this is EAST AFRICAN RIFT zone. |
| How do tectonic forces create fault block mountains? | Tectonic forces EXERTED in OPPOSITE directions cause fault block mountains to FORM |
| (true or false) through earths history, rock strata have piled up and become highly folded along mid-ocean ridges | False |
| what process affects all rocks after they have formed? What kind of earth materials does this process create? | EROSION affects all rocks after after they form. The process of EROSION produces SEDIMENTS |
| How are sediments moved about? | gravity, wind, flowing water |
| what kind of depositional mountains or hills are formed by wind? | sand dunes |
| why are volcanoes considered depositional mountains | volcanoes BUILD up when lLIQUID and SOLID rock materials from ERUPTIONS are DEPOSITED on the earth’s surfaces |
| (True or false) some “fossilized”sand dunes seen in sand stone formations may have actually formed underwater | true |
| Compare and contrast anticlines, synclines, and monoclines | a. Anticlines- occur as an upward fold B. Synclines- a downward fold C. Monoclines- one side of the fold pushed up or dropped compared to the other side of the fold |
| What is another name for the valley like formations found in rift systems | grabens |
| mesas are to buttes as mountains are to | hills |
| The term used by geologists to describe the balance of the weights of rock, water, and ice and the upward force if the mantel | isostasy |
| a “natural” elevation of the earth’s surface rising more or less abruptly to a summit | mountain |
| what is the highest mountain on earth | Mt. Everest |
| a series of mountain peaks in the same geographical area | mountain range |
| where is the longest mountain system and what is it called | Is under the Atlantic Ocean and Mid Atlantic Ridge |
| are broad regions of relatively undisturbed sedimentary deposits lifted by some tectonic process | plateaus |
| which state is almost entirely a single basin structure | Michigan |
| Are extinct volcanoes in ocean basins | seamounts |
| Also called residual mountains are mountains that were carved out by extensive erosion, usually from a plateau | erosional mountains |
| are long, relatively low ridges of glacial tilt that form mostly at the front and sides of glaciers | moraines |
| what is the geologic term for tectonic mountain building | |
