How Can Movement of Different Tectonic Plates Be Explained

Divergent BoundaryThis occurs when two tectonic plates move away from each other. There are three main types of boundaries.

Are you a high school student who would rather not spend every night studying and working on homework.

. Tectonic plates are able to move because Earths lithosphere has greater mechanical strength than the underlying asthenosphere. The geoscientific community has accepted the plate tectonic theory after obtaining significant proof on the seafloor spreading. How do plate tectonics REALLY workPlease support us on Patreon at.

The relative movement of the plates typically ranges from zero to 100 mm annually. I am here to help you find the answers you need quickly so. Transform convergent and divergent.

Hot magma rises to the crusts surface cracks develop in the ocean floor and the magma pushes up and. When continents on two different plates are apart thick sequences of sediments can be laid down on top of the oceanic plate in between them. When the plates move apart a fissure opens up and the molten rock rushes from the mantle to the surface.

These currents are warm and they can carry and drive the tectonic plates that make up the lithosphere in a way. They can coliide head-on we call this a convergent boundary they can move away from each other a divergent boundary or slide sideways ex. The opening or fissure helps lower the pressure of the mantle layer and allows the molten material to the surface.

A divergent boundary occurs when two tectonic plates move away from each other. Vladimir1956 14 1 year ago. Magma formed from melting plates solidifies into granite a light colored low-density rock that makes up the continents.

Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earths subterranean movements. Along these boundaries earthquakes are common and magma molten rock rises from the Earths mantle to the surface solidifying to create. Last week I did a scientist classroom visit for about 60 eight-year-olds.

Thus at convergent boundaries continental crust made of granite is created and oceanic crust is destroyed. Convection currents in the liquid mantle cause the plates to move. There is still some debate as to whether asthenospheric convection drives the plates or the plates themselves drive plate tectonics.

At transform boundaries plates move past each other. Volcanic activity earthquakes mountain-building and oceanic trench formation occur along these plate boundaries. A combination of dragging the lithosphere along the top of the convection cell ridge push sliding and slab pull all appear to be contributing factors to the cause of plate tectonics.

Convection currents drive the movement of Earths rigid tectonic plates in the planets fluid molten mantle. Lateral density variations in the mantle result in convection. The Earths lithosphere which includes the crust and upper mantle is made up of a series of pieces or tectonic plates that move slowly over time.

Two plates can move in 3 major ways where they contact each other. This is one of the most common causes of earthquakes. All of these reasons boil down to various forces that are creating the movement.

Plate tectonics is a scientific theory that describes the large-scale movement and the distribution of the plates that make up the earths lithosphere. When these plates meet their relative motion determines the type of boundary like convergent divergent or transform. Movement of tectonic plates.

One plate moves North and. Answer 1 of 4. In places where convection currents rise up towards the crusts surface tectonic plates move away from each other in a process known as seafloor spreading Fig.

If a subduction zone develops in this oceanic area one of the plates is carried down subducted into the mantle and the continents are moved towards each other. At convergent boundaries plates move toward each other. That is the slow creeping motion of Earths solid mantle.

The edges or boundaries of tectonic plates meet up in different ways. Natural or human-made structures that cross a transform. Competitive exclusion is most likely to occur between two A closely related species occupying different niches B closely rel.

The first of the possible reasons is the mantle convection currents. Researchers have proposed three main reasons why the tectonic plates are moving. The theory which solidified in the 1960s transformed the earth sciences by explaining many phenomena including mountain building events volcanoes and earthquakes.

Explain how the movement of tectonic plates can affect local environments. I showed them a rock with a lot of fossils in it along with some pictures of broken clam shells to help them understand what they were seeing. The plate tectonic theory is built from the concept of the sliding and movement of the continents.

Two plates sliding past each other forms a transform plate boundary. In plate tectonics Earths outermost layer or lithosphere. At the top of the mantle the rock encounters the thin crust and as it pushes it aside lava flows out from the mantle to form.
