What is divergent tectonic plates kids?

Divergent boundaries A divergent boundary is an area where two crustal plates are separating. Most of these tectonic plate boundaries are located on the floor of the oceans. The separating plates form rift valleys on the ocean floor where there are weaknesses in the crust.

What are the tectonic microplates?

Microplates are small mostly rigid areas of lithosphere, located at major plate boundaries but rotating as more or less independent plates. They can form in many tectonic settings. The two main types along mid-ocean ridges, those formed at and away from triple junctions, share many similarities.

What are plate tectonics simple explanation?

Plate tectonics is the theory that Earth’s outer shell is divided into large slabs of solid rock, called “plates,” that glide over Earth’s mantle, the rocky inner layer above Earth’s core. Earth’s solid outer layer, which includes the crust and the uppermost mantle, is called the lithosphere.

What is a divergent tectonic plate?

Divergent (Spreading):This is where two plates move away from each other. Molten rock from the mantle erupts along the opening, forming new crust. The earthquakes that occur along these zones, called spreading centers, are relatively small.

What causes the movement of tectonic plates for kids?

These plates move because of heat from Earth’s core. Earth’s radioactive core generates an immense amount of heat that keeps our planet from completely cooling over. Less dense molten rock travels from the core to the surface, where it then cools and returns—a process called convection.

What is diverging tectonic plates?

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 is an example of divergent plate boundaries.

What is the difference between converging or diverging?

Converging lenses are lenses which converge the light rays coming towards them, whereas diverging lenses are lenses which diverge the rays coming towards them. A converging lens have positive focal length.

What is the difference between convergent and divergent 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.

What is the theory of plate tectonics Quizlet?

The theory, or idea, of plate tectonics says that Earth’s outer layer is made up of large, moving pieces called plates. All of Earth’s land and water sit on these plates. The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock.

How many miles thick are tectonic plates?

Tectonic plates are around 62 miles thick. There are two main types of tectonic plates: oceanic and continental. Oceanic – Oceanic plates consist of an oceanic crust called “sima”.

How do scientists track the movement of tectonic plates?

Scientists are now able to track the movement of tectonic plates using GPS. The Himalayan Mountains, including Mount Everest, were formed by the convergent boundary of the Indian Plate and the Eurasian Plate.

How do the plates interact at their boundaries?

The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock. The plates are constantly moving over this weaker layer. As the plates move, they interact at their boundaries in different ways. At one type of boundary the plates slide alongside each other.
