What is it called when two plates move next to each other?
Also called lithospheric plate. site of tectonic plates sliding next to each other in opposite directions. Also called a transform fault. boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other. Also called a conservative plate boundary.
What is the area where two or more plates bump into each other?
area where two or more tectonic plates bump into each other. Also called a collision zone. area where two or more tectonic plates are moving away from each other. Also called an extensional boundary. the sudden shaking of Earth's crust caused by the release of energy along fault lines or from volcanic activity.
What is the boundary between two tectonic plates?
boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other. Also called a conservative plate boundary. long, deep depression, either natural or man-made.
Can a single plate have multiple types of plate boundaries?
A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. For instance, the Pacific Plate, one of Earth’s largest tectonic plates, includes convergent, divergent, and transform plate boundaries.

What term describes when one plate comes in contact with another?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common at subduction zones as well.
Where do tectonic plates meet?
plate boundariesThe Earth's outer shell is divided into pieces called plates. Most volcanoes, mountains, and earthquakes occur where plates meet. Places where plates meet are called plate boundaries.
What are 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 the plates that move away past or towards each other?
Motion between tectonic plates can be divergent , convergent , or transform . In divergent boundaries, plates are moving away from each other; in convergent boundaries, plates are moving toward each other; and in transform boundaries, plates are sliding past each other.
What is it called when tectonic plates collide?
Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
What are the 3 main types of plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.
What are 4 types of plate boundaries?
Plate Boundaries and Hotspot DemonstrationDivergent Plate Boundary. Volcanic eruptions and shallow earthquakes are common where plates rip apart.Convergent Plate Boundary. ... Transform Plate Boundary. ... Hotspot.
What are the 4 types of plate movements?
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. Microplates are smaller fragments of tectonic plates that appear in plate boundary zones.
What are different types of plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
How do plates interact with each other?
Tectonic plates can interact in one of three ways. They can move toward one another, or converge; move away from one another, or diverge; or slide past one another, a movement known as transform motion. All plate margins along which plate movement is occurring have one thing in common—earthquakes.
What are the 3 ways tectonic plates move?
How Earth's Plates Move Lesson #3Convergent boundaries - two plates collide to form mountains or a subduction zone.Divergent boundary - two plates are moving in opposite directions as in a mid-ocean ridge.Transform boundary - two plates are sliding past each other as in the San Andreas fault of California.
How do the two plates move relative to each other?
At transform boundaries, plates move past each other. This is one of the most common causes of earthquakes. At convergent boundaries, plates move toward each other. They can push together and cause mountain ranges to form.
How do tectonic plates fit together?
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other.
What tectonic plate is South Africa part of?
African PlateThe African Plate is a major tectonic plate straddling the Equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges.
What are the 12 plate boundaries?
The Earth's major tectonic plates are:African Plate.Antarctic Plate.Eurasian Plate.Australian Plate.North American Plate.Pacific Plate.South American Plate.
How many tectonic plates are on the earth?
The surface of the Earth is divided into 7 major and 8 minor plates. The largest plates are the Antarctic, Eurasian, and North American plates.
How is C. separated from the mantle?
C. is separated from the mantle by the Moho.
Which two planets hold the A. together?
A. is held together by the gravitational pulls of Jupiter and Saturn.
What is the area where two or more tectonic plates bump into each other?
area where two or more tectonic plates bump into each other. Also called a collision zone.
Which plate boundary is responsible for many earthquakes?
A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. For instance, the Pacific Plate, one of Earth’s largest tectonic plates, includes convergent, divergent, ...
What is the boundary between the Indian Plate and the Eurasian Plate?
Typically, a convergent plate boundary —such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward. In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another.
What is a divergent plate boundary?
A divergent plate boundary often forms a mountain chain known as a ridge . This feature forms as magma escapes into the space between the spreading tectonic plates. One example of a ridge is the Mid-Atlantic Ridge, an undersea chain of mountains that formed as two pairs of tectonic plates spread apart: the North American Plate and the Eurasian Plate in the north, and the South American Plate and the African Plate in the south. Because ocean ridges are found underwater, often at great depths, they can be hard to study. In fact, scientists know more about the surfaces of some of the other planets in our solar system than they do about ocean ridges.
Why are volcanoes found near plate boundaries?
Volcanoes are also often found near plate boundaries because molten rock from deep within Earth—called magma—can travel upward at these intersections between plates . There are many different types of plate boundaries. For example, sections of Earth’s crust can come together and collide (a “convergent” plate boundary), ...
Why are plate boundaries important?
Plate boundaries are important because they are often associated with earthquakes and volcanoes. When Earth’s tectonic plates grind past one another, enormous amounts of energy can be released in the form of earthquakes. Volcanoes are also often found near plate boundaries because molten rock from deep within Earth—called magma—can travel upward ...
What is transform fault?
Noun. boundary between two tectonic plates, where the plates are moving horizontally or vertically in opposite directions, not against or away from each other. Also called a conservative plate boundary. trench. Noun. long, deep depression, either natural or man-made.
How is C. separated from the mantle?
C. is separated from the mantle by the Moho.
Which two planets hold the A. together?
