How do you determine cleavage?
Regional SpecificsAsked by: April Harris To determine the angle of cleavage, look at the intersection of cleavage planes. Commonly, cleavage planes will intersect at 60°, 90° (right angles), or 120°. Be cautious when you see a flat surface on a mineral – not every flat surface is a cleavage plane. How do you identify cleavage and
What would you be most likely to find at a divergent boundary between two pieces of continental crust?
Regional SpecificsAsked by: Jay Betoch A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundariesplate boundariesIf two tectonic plates
How are U shaped and V shaped valleys formed?
Regional SpecificsAsked by: Suzanne Gerrans Valley glaciers carve U-shaped valleysU-shaped valleysU-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. How are U-shaped valleys formed simple? Glaciers cut distinctive U-shaped valleys , or troughs, with a flat floor and steep sides. The
How did the Himalayan mountains form quizlet?
Regional SpecificsAsked by: Andy Singh The Himalayas were formed due to the collision between the Eurasian Plate and the Indian Plate. When Asia and Europe collided, subduction stopped because India could not sink into the mantle. Since it could not sink, the Indian Plate pushed the crust upward and also downward, because of this, the Himalayas
What is the process which causes magma to form?
Regional SpecificsAsked by: Nicole Young Magma is created at mid-ocean ridges via decompression melting. Strong convection currents cause the solid asthenosphere to slowly flow beneath the lithosphere. The upper part of the lithosphere (crust) is a poor heat conductor, so the temperature remains about the same throughout the underlying mantle material. What causes magma to form?
Why are the Appalachian mountains so important?
Regional SpecificsAsked by: Jesse Carmody The mountains have played an important role in the history and economic development of the United States. They formed a barrier that held the early settlers near the Atlantic coast until the colonies could develop the unity and strength to fight for independence and form a nation. What makes Appalachia unique?
