What causes the offsets in the mid oceanic ridge system?
Regional SpecificsOceanic ridges offset by transform faults and fracture zones. The arrows show the direction of movement across the transform faults. What causes the offsets along the Mid Oceanic Ridge system? Due to the fast spreading rates, there is no rift valley, just a smooth volcanic summit with a crack along the crest that is much
Where is limonite found?
Regional SpecificsSome limonite is found in stratified deposits where hydrous iron oxides form as precipitated sediment on the floor of shallow swamps, lakes, and marine environments.… Physical Properties of Limonite Chemical Classification Amorphous, mineraloid Chemical Composition A hydrated iron oxide of variable composition Where in the world is limonite found? Limonite is a very common mineral
Why is Granite The most common plutonic rock?
Regional Specificsgranite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth. Why is granite The most common igneous rock? Because they form within the Earth, cooling occurs slowly. Such slow cooling
What are 5 interesting facts about tsunamis?
Regional SpecificsFact 1: An underwater earthquake, a volcano eruption or a landslide mostly causes a tsunami. Fact 2: Only on very few occasions a tsunami is caused by a giant meteor in the ocean. Fact 3: Tsunami waves can be as huge as 100 feet. Fact 4: About 80% of the tsunamis occur in the Pacific
What are fault lines Why are they significant?
Regional SpecificsThe composition of Earth’s tectonic plates means that they cannot glide past each other easily along fault lines, and instead produce incredible amounts of friction. On occasion, the movement stops, causing stress to build up in rocks until it reaches a threshold. What are fault lines? A fault line is a long crack in the
