Where is the world’s water found?

Asked by: Donald Hands the oceans Where is the worlds water found? Earth’s water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground. Where does the world’s

What does intrusive igneous mean?

Asked by: Kirk Wallace In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. What is the meaning of intrusive igneous rock? Intrusive, or plutonic, igneous rock forms when magma is trapped deep

How do you determine cleavage?

Asked 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?

Asked 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?

Asked 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?

Asked 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?

Asked 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?

Asked 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?

What causes mass wasting?

Asked by: Joseph Fulce Mass-wasting events are triggered by changes that oversteepen slope angles and weaken slope stability, such as rapid snow melt, intense rainfall, earthquake shaking, volcanic eruption, storm waves, stream erosion, and human activities. Excessive precipitation is the most common trigger. What triggers mass wasting? Mass-wasting events often have a trigger: something changes

What is the interaction between the atmosphere and hydrosphere?

Asked by: Malaysy Bottenhagen Plants (atmosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. Plants (hydrosphere) draw water (biosphere) and nutrients from the soil and release water vapor into the atmosphere. What is the interaction between the atmosphere and biosphere? Biosphere-Atmosphere Interactions focuses on the sources and sinks
