What is a geologic event that occurs when tectonic plates are shifted violently?
Earthquake. This is a geologic event that occurs when tectonic plates are shifted violently.
What are the geological events that happen due to plate movements?
These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
What is it called when a tectonic plate suddenly moves?
Earthquakes are the result of sudden movement along faults within the Earth.
What is convergent boundary?
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.
Is igneous sedimentary or metamorphic?
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
What are the geologic processes events that will occur because of convergence of two oceanic plates?
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.
What geologic processes events that will occur because of the collision between two oceanic plates?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
What are tectonic earthquakes?
Tectonic earthquakes are produced by sudden movement along faults and plate boundaries. Earthquakes induced by rising lava or magma beneath active volcanoes is called volcanic earthquakes.
What type of earthquake occurs when two tectonic plates move suddenly against each other?
The earthquakes that occur along these zones, called spreading centers, are relatively small. The Great Rift Valley in Africa, the Red Sea and the Gulf of Aden all formed as a result of divergent plate motion. Convergent (Colliding): This occurs when plates move towards each other and collide.
What is a divergent boundary?
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.
What is convergent movement?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate.
What are the uses of rocks and minerals Class 7?
Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances. In order maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily.
How do extrusive igneous rocks differ from intrusive igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
What are the geologic processes events that will occur because of this plate movement you can choose 4 answers?

What are the geologic processes?
Geological processes – volcanoes, earthquakes, rock cycle, landslides Plate boundaries include transform, convergent , divergent. Theory of Continental Drift – The continents were once joined together in one large continent called Pangea.
What are the geologic processes or events that may occur in an oceanic oceanic convergence?
These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere.
What is it called when two plates collide?
A convergent plate boundary is formed when tectonic plates collide.
Which type of earthquake occurs due to the movement of tectonic plates?
tectonic earthquakes The most common are tectonic earthquakes. These occur when rocks in the earth's crust break due to geological forces created by movement of tectonic plates.
What causes of tectonic earthquake?
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
Which event takes place when two tectonic plates move away from each other?
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 geologic process take place in divergent plate boundary?
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 divergent convergent and transform?
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. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What is convergent in geography?
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.
How are extrusive and intrusive rocks formed short answer?
Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
How can you promote the sustainable development in utilizing rocks as a student?
Recycling materials make an important contribution to the sustainable use of rocks and minerals. Most metals can be recovered and refined back to clean metals to be used by industries again. This uses less energy than processing the ores or concentrates to make metals.
How does the rate of cooling affect the formation of intrusive igneous rocks of extrusive igneous rocks Brainly?
Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So igneous extrusive rocks have smaller crystals than igneous intrusive rocks.
How do light colored igneous rocks differ from dark colored rocks?
Light-colored igneous rocks are more granitic (felsic) in composition and contain more feldspar and silica. Dark-colored igneous rocks are more basaltic (mafic) in composition and contain more iron and magnesium.
What are the geologic processes or events?
Geologic Processes Deformation – responsible for earthquakes, volcanism, landslides, subsidence. Isostatic Adjustment due to buoyancy – responsible for earthquakes, landslides, subsidence. Weathering – responsible for landslides, subsidence. Erosion – responsible for landslides, subsidence, flooding.
What are the 4 geologic processes?
Geological processes
- Erosion. Erosion involves the movement of rock fragments through gravity, wind, rain, rivers, oceans and glaciers.
- Weathering. Weathering is the wearing down or breaking of rocks while they are in place.

- Landforms. …
- Relief.
What causes the geological events to happen?
What Causes Geological Activity? Geological Activity can be defined as the movement of tectonic plates beneath Earth's surface. One of the main components for geological activity to be present is heat. In order for plates to move there must be heat.
