Answer 1

Answer:

The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.

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 and Pacific Ring of Fire are two examples of divergent plate boundaries.

When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these 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.

Two plates sliding past each other forms a transform plate boundary. One of the most famous transform plate boundaries occurs at the San Andreas fault zone, which extends underwater. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. Earthquakes are common along these faults. In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed.

Answer 2

Answer:

Explanation:

What are the types of plate movements? How do they occur?

The Earth's crust is broken up into a number of plates that are constantly moving across the globe. Geologists have given names to the types of ways these plates interact with one another to shape the geological world we live in.

These are the types of ways plates can interact with one another:

Constructive / Divergent plate margins is when two plates are moving apart. This causes magma (molten rock) from below to rise up, filling in the gap and cooling down from the cooler temperatures above. This creates a new crust. An example of this happening as along the mid-ocean ridge in the Atlantic Ocean.

Destructive / Convergent plate margins are when two plates are moving towards each other, but one is heavier than the other. Usually this is the case between an oceanic plate and a continental plate. Oceanic plates are plates that are mostly under sea, while continental plates are mostly land. As oceanic plates are heavier they get submerged under the continental plate. This is called subduction, and is the cause of volcanoes from the sudden rising of magma pressing against the crust.

Collision margins are similar to convergent margins, except in this case, both plates are roughly of equal weight (so presumably both are continental plates or both are oceanic plates) and therefore their force against each other is equal. One cannot subduct under the other. So in this case, both smash against each other, giving rise to fold mountains such as the Himalayas. The creases in the plates creates the mountains.

Conservative margins are when two plates are sliding past each other, rather than moving to or away from one another. This is a cause of earthquakes as the plate boundaries are uneven, and so will click against one another, causing earth quakes. Since no magma rises from this action, and there is no subduction, volcanoes do not form from this action
