What are the 3 types of boundaries mark plate movements?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other.

Are andesitic volcanoes convergent or divergent?

Granitic, or rhyolitic, magmas and andesitic magmas are generated at convergent plate boundaries where the oceanic lithosphere (the outer layer of Earth composed of the crust and upper mantle) is subducted so that its edge is positioned below the edge of the continental plate or another oceanic plate.

What type of plate boundary creates andesite Stratovolcanoes?

Composite volcanoes, also known as stratovolcanoes, are found on convergent plate boundaries , where the oceanic crust subducts beneath the continental crust.

What are the 4 types of tectonic plate boundaries?

There are four types of boundaries between tectonic plates that are defined by the movement of the plates: divergent and convergent boundaries, transform fault boundaries, and plate boundary zones.

What do each plate boundaries form?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.

What is an example of a convergent plate boundary?

The Pacific Ring of Fire is an example of a convergent plate boundary. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents.

What type of volcano is andesitic?

Andesite magma commonly erupts from stratovolcanoes as thick lava flows, some reaching several km in length. Andesite magma can also generate strong explosive eruptions to form pyroclastic flows and surges and enormous eruption columns. Andesites erupt at temperatures between 900 and 1100 ° C.

What type of plate boundary is associated with rhyolite?

Convergent plate boundaries
Igneous rocks associated with convergent plate boundaries have the greatest diversity. In this case, granite batholiths underlie the great composite volcanoes and consist of rocks ranging from basalt through andesite to dacite and rhyolite.

Where is rhyolite found?

Rhyolite has the mineralogical composition of granite. Rhyolite rocks can be found in many countries including New Zealand, Germany, Iceland, India, and China, and the deposits can be found near active or extinct volcanoes.

How will you describe each type of plate boundary?

Convergent boundaries — where crust is destroyed as one plate dives under another. Divergent boundaries: where new crust is generated as the plates pull away from each other. Convergent boundaries: where crust is destroyed as one plate dives under another.
