What are the 3 main types of plate boundaries and each subtype?

What are the 3 main types of plate boundaries and each subtype?

There are three main types of plate boundaries:

• Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
• Divergent boundaries – where two plates are moving apart.
• Transform boundaries – where plates slide passed each other.

What are the 3 types of plate boundaries?

• 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.
• Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.

What are the three types of convergent plate boundaries quizlet?

• Oceanic-continental convergence.
• Oceanic-oceanic convergence.
• Continental-Continental convergence.

What are three types of convergent boundaries answers?

Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.

• Continent‐continent convergence results when two continents collide.
• Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.

What happens to plates at convergent boundaries?

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. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

What are the effects of the three types of convergent plate boundaries?

Effects that are found at this type of plate boundary include: a zone of progressively deeper earthquakes; an oceanic trench; a chain of volcanic islands; the destruction of oceanic lithosphere.

What landforms are created by convergent boundaries?

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 features are created at divergent boundaries?

Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.

What are the 3 processes that create landforms?

The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes….

How are riverines formed?

A riverine is a landscape formed by the natural movement of a water system such as a river. A riverine landscape includes the ecosystems (all living things including plants and animals) in and around the area of a river. A riverine may also be defined as a network of rivers and the surrounding land.

How do humans impact the landscape?

Many human activities increase the rate at which natural processes, such as weathering and erosion, shape the landscape. The cutting of forests exposes more soil to wind and water erosion. Pollution such as acid rain often speeds up the weathering, or breakdown, of the Earths rocky surface.

What is riverine flood?

Riverine flooding is caused by bank overtopping when the flow capacity of rivers is exceeded locally. The rising water levels generally originate from heavy snowmelt or high-intensity rainfall creating soil saturation and large runoff – locally or in upstream catchment areas.

How are rivers formed answers?

river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas….

Do All Rivers Flow to the Sea?

Where do rivers end? The great majority of rivers eventually flow into a larger body of water, like an ocean, sea, or large lake. The end of the river is called the mouth.

Why do rivers flow down to the sea?

Answer. Water always moves down the slope, i.e., from higher elevation to lower elevation. And sea is always at a lower elevation. So water flow down to the sea….

Can the ocean overflow?

Rivers may flow, but oceans will never overflow….

Are rivers and oceans connected?

Rivers come in lots of different shapes and sizes, but they all have some things in common. All rivers and streams start at some high point. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake. …

What is it called where a river ends?

A river usually ends by flowing into an ocean, a lake or a bigger river. The place where the river flows out into a bigger body of water is called the ‘mouth’ of the river. As a river flows towards its mouth, the countryside around the river often changes from hilly to flat.
