Earth Science
Chapter 7 Study Guide
| Question | Answer |
|---|---|
| The Himalaya Mountains | Have high relief |
| The Great Plains in the Midwest United States | Has low relief |
| Where is the most extensive mountain system in 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 the East African Rift zone. |
| How do tectonic forces create fault-block mountains? | Tectonic forces exerted in opposition directions cause fault-block mountains to form |
| (True or False) Through Earth's history, rock strata have piled up and became 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 rock 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 is formed by wind? | Sand and Dunes |
| Why are volcanoes considered depositional mountains? | Volcanoes build up when liquid and solid rock materials from eruptions are deposited on the Earth's surface. |
| (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 | Anticlines - occurs as an upward fold Synclines - a downward fold Monoclines - one side of the fold pushes up or dropped compared to the outer 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 or rock, water, and ice and the upward force of 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, 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 basin | 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 till that form mostly at the front and sides of glaciers | Moraines |
| What is the geologic term for tectonic mountain building? | Orogeny |
