What are the 4 types of tectonic plate movements and what do they create?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
What do transform boundaries create?
The Earth’s crust is split into sections called tectonic plates. Transform boundaries are where two of these plates are sliding alongside each other. This causes intense earthquakes, the formation of thin linear valleys, and split river beds.
What are the 3 types of plate boundaries and what do they cause?
Tectonic Plates and 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 geologic features are formed in each boundary?
Types of Geography Features at a Plate Boundary
- Fault Lines. A transform boundary connects two diverging boundaries, creating a fault line.
- Trenches. Trenches are geological features formed by convergent boundaries.
- Volcanoes.
- Mountain Ranges.
- Ridges.
- Rift Valleys.
Do divergent plate boundaries create volcanoes?
Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another.
What do divergent boundaries create?
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 convergent boundary Brainly?
Convergent boundaries are areas where plates move toward each other and collide.
What does divergent plate boundaries cause?
When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes.
What geological features are created at divergent plate boundaries?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
What geological feature is formed in a divergent 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.
What is a real life example of a divergent boundary?
The mid-Atlantic ridge is an example of a divergent boundary, where the Eurasian Plate that covers all of Europe separates from the North American Plate . This underwater mountain range is constantly growing as new crust is formed.
What causes a transform boundary?
Transform boundaries occur where plates are sliding past each other. When oceanic plates collide with continental plates, the denser oceanic plate is forced under the lighter continental plate. This process has three geological results. The continental plate is lifted upwards, creating mountains. As the oceanic plate subducts, a trench is formed.
What landforms are caused by transform boundaries?
One of the primary landforms that is produced by a transform boundary is a fault. Typically known as strike-slip faults, they build up pressure when friction prevents them from sliding until the pressure exceeds the force of the friction and results in an earthquake.
What happens at transform boundaries?
Seafloor Spreading. Most transform boundaries consist of short faults on the seafloor occurring near mid-ocean ridges.
