What is a volcano?
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.

What boundary makes the Plate tectonics scrape against each other?
What is a Transform Boundary.

What are mountains?
A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth.

Where do Convection Currents occur?
Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the asthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.

What are the core, the crust and the mantle?

How do volcanoes form?
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.

What boundary is also named the destructive boundary?
What is a Convergent Boundary?

How are mountains form?
Movements 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.

What causes Convection Currents
Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Or when a cooler material sinks in an liquid.

What are the Hydrosphere,Biosphere Atmosphere and the Lithosphere.

What is a dormant volcano?
An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. A dormant volcano is an active volcano that is not erupting, but supposed to erupt again.

What Boundary has to deal with rift valleys?
In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts which eventually become rift valleys.

Mount Kilimanjaro.

What are Convection Currents?
In astronomy convection currents occur in the mantle of the Earth, and presumably some other planets, and the convection zone of the sun. Inside of the Earth, magma is heated near the core, rises toward the crust, then cools and sinks back toward the core.

What is magma?
Magma is the molten or semi-molten natural material from which all igneous rocks are derived. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. 
400
What is a plate boundary?
A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth's surface between the two plates. The middle of the Red Sea and the mid-ocean ridge (running the length of the Atlantic Ocean) are divergent plate boundaries.

What is Lava?
Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption, usually at temperatures from 700 to 1,200 °C. The structures resulting from subsequent solidification and cooling are also sometimes described as lava.
