Answer:
Silicate-Oxygen tetrahedro
Explanation:
Silicate-Oxygen tetrahedro are the most abundant and basic structure of common minerals.
These are silicate minerals which formed to silicate rock forming mineral. These constitute about 90% of earth crust. Silica SiO2 consider as most common mineral on the surface of earth also known as Quartz. The the most andundant element in the earth crust is oxygen, mainly found in combine form.
Answer:
Sierra Madre Occidental
Explanation:
this mountain range takes up nearly 140,000 square miles of Mexico.
Answer:
The Great Lakes began to form at the end of the last glacial period around 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land which then filled
The naval strategy is the preparation and execution of combat at sea. Naval strategy and the associated theory of maritime strategy involves the comprehensive strategy for gaining supremacy at sea, which includes the planning and execution of operations, the action and disposition of naval units by which a leader achieves the benefit of struggling at a place accessible to himself, and the deception of the opponent. The following are the fundamental functions of the U.S. Navy, Marine Corps, and Coast Guard in the execution of the National Naval Strategy:
1. Secure strategic passage and maintain the global choice of action.
2. Extend existing and developing partnerships and alliances
3. Secure favorable defense requirements
4. guard the U.S. against direct invasion
The correct answer is - 5) At a normal fault, tensional stress causes the hanging wall block to move downward with respect to the foot wall block. Conversely, at a reverse fault, compressional stress causes the hanging wall block to move upward with respect to the foot wall block.
Both the normal faults and the reverse faults are dip-slip faults, meaning that they experience vertical movement which is inline with the dip of the fault. Both of them can be identified by the relative movement of their hanging walls and foot wall.
The normal faults have a hanging wall that is moving downwards relative to the foot wall. This kind of movement is caused by extensional tectonics, or rather by tensional stress. The faulted section of the rocks is lengthened because of this type of processes.
The reverse faults have a hanging wall that moves upward relative to the foot wall, thus the total opposite of the normal fault. This kind of movement is caused by the compressional tectonics. The faulted section of the rocks shortens under this type of processes.
