What are the geologic processes events that will occur when two oceanic plates collide?
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. ... Earthquakes generated in a subduction zone can also give rise to tsunamis.
What are examples of sudden geological changes?
Capture students’ interest and find out what they know about the sudden geological changes and extreme weather conditions, e.g. earthquakes, tsunamis, volcanic eruptions, floods, cyclones, and droughts .
What are examples of geological processes?

- Subsidence.
- Floods.
- Droughts.
- Hurricanes.
What are the geological events?
- Caves.
- Deserts.
- Earthquakes.
- Glaciers.
- Tsunamis.
- Volcanoes.
What happens when two oceanic plate collide?
When two oceanic plates collide one oceanic plate is eventually subducted under the other . Where one plate slides under the other is referred to as the ‘subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.
Can you describe what geological features are formed on top of plate A?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
What happens when two oceanic plates diverge?
The plates diverge and this causes the construction of new rock . It happens when two tectonic plates pull apart and rock from the mantle rises up through the opening to form new surface rock when it cools. It happens at the start of a new ocean and continues at the mid-ocean ridge while the ocean is opening.
What is a sudden geological change?
Sudden geological changes and extreme weather events can affect Earth’s surface (ACSSU096) Elaborations. investigating major geological events such as earthquakes, volcanic eruptions and tsunamis in Australia, the Asia region and throughout the world. recognising that earthquakes can cause tsunamis.
What are examples of extreme weather events?
- Tornado: clouds, strong wind, rain, hail.
- Hurricane or cyclone: strong wind, heavy rain.
- Blizzard: heavy snow, ice, cold temperatures.
- Dust storm: strong winds, arid conditions.
- Flood: heavy rainfall.
- Hail storm: cold or warm temperatures, rain, ice.
- Ice storm: freezing rain.
Can natural events on Earth cause sudden changes?
Changes to Earth can happen suddenly or over long periods of time. Earthquakes, volcanoes, tsunamis and landslides are naturally occurring events that can rapidly change Earth’s surface.
What are 4 geological processes and where do they occur?
The four major geological processes are impact cratering, volcanism, tectonics, and erosion . Earth has experienced many impacts, but most craters have been erased by other processes. We owe the existence of our atmosphere and oceans to volcanic outgassing.
What are the 5 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.
- Deposition. ...
- Landforms. ...
- Relief.
What is the importance of geological processes?
Geologists study Earth processes: Many processes such as landslides, earthquakes, floods, and volcanic eruptions can be hazardous to people . Geologists work to understand these processes well enough to avoid building important structures where they might be damaged.
What forms when two of Earth’s plates pull apart?
When two continental plates diverge, a valleylike rift develops . This rift is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do volcanoes, which may become increasingly active.
What happens when two oceanic plates collide quizlet?
What happens when two oceanic plates collide? When two oceanic plates collide, the denser plate is subducted and some material rises upward and forms an ISLAND . ... Ocean floor is pushed away from a midocean ridge to form new sea floor.
