What is the difference between continents and ocean basins quizlet?
GeologyWhat is the difference between continents and ocean basins? Ocean basins are made of thin basaltic material that is denser. Continents are made of thick granitic material that is less dense. What is the difference between continents and ocean basins? Continents are large and continuous masses of land which are separated by expanses of water.

What is basal melting?
GeologyBasal melt The melting point of water decreases under pressure, meaning that water melts at a lower temperature under thicker glaciers. What causes basal melting? Basal melting is primarily the result of geothermal heating and pressure of the ice mass. What is basal temperature glaciers? The basal temperature gradient (figure 2) determines the extent to

How do you identify moraines?
GeologyLateral moraines are usually found in matching ridges on either side of the glacier. The glacier pushes material up the sides of the valley at about the same time, so lateral moraines usually have similar heights. If a glacier melts, the lateral moraine will often remain as the high rims of a valley. What are

Is Marble A granite?
GeologyGranite is an igneous rock, which means it was once molten and formed as it cooled deep within the earth. The minerals contained in granite usually appear as small flecks throughout the stone. Marble, on the other hand, was once limestone that changed due to intense heat and pressure. Is marble and granite the same?

How do volcanoes affect the rock cycle?
GeologyExplanation: magma which can be made of melted sedimentary rocks and metamorphic rocks. These melted rocks are then turned into igneous rocks. The igneous rocks are then eroded and turned into sedimentary rocks. How did volcanic eruption affect the formation of rocks? When volcanoes violently erupt, many gas bubbles form in the lava, so it

How high are mid ocean ridges?
GeologyA mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary. Are mid-ocean ridges

What are the two type of mining?
GeologyMining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores. What are the 2 types of mining? There are two basic

How do volcanoes form in a folded mountain range?
GeologyMovements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust. How is a volcano formed differently from a

How far would the Yellowstone eruption reach?
GeologyThe eruption could be expected to kill as many as 90,000 people immediately and spread a 10-foot (3-meter) layer of molten ash as far as 1,000 miles (1,609 kilometers) from the park. How far will Yellowstone reach if it erupts? The devastation would not be restricted to the local environment. Yellowstone’s plume of ash, lava,
