Since the plates pull apart from each other, a volcano is formed. Magma will push its way up through the cracks found between the plates onto the Earth's surface. The magma reaches the Earth's surface as lava. Lava and magma are made of the same substance. The process by which magma and other materials reach the Earth's surface is called vulcanicity. The outpouring of the lava to the surrounding areas is called an eruption. This is caused by the build-up pressure caused by gases below the Earth's surface. The magma may flow out onto the Earth's surface quietly or be accompanied by violent eruptions. The lava hardens on the Earth's surface as the temperature is cooler. The hardened lava built up from many eruptions results in a cone-shaped mountain called a volcano.
Hope it helped :)
What else can I help you with?
What are 2 landforms that are created at by oceanic oceanic crust?
Two landforms created by oceanic-oceanic crust interactions are oceanic ridges and volcanic islands. Oceanic ridges form at divergent plate boundaries where two oceanic plates move apart and magma rises to create new crust. Volcanic islands, on the other hand, form where two oceanic plates converge and one plate subducts beneath the other, leading to volcanic activity and the formation of islands.
Compare and contrast the three plate boundaries?
Oceanic-continental convergence (when an oceanic plate meets a continental plate) & oceanic-oceanic convergence (2 oceanic plates) both involve oceanic plates & subduction. Continental-continental convergence (2 continental plates) involves neither.
What is the difference between oceanic plate and continential plate?
Oceanic plates are young and made of basalt and recent sediments. Continental plates are old and contain continental crust made of old rocks and they are usually considerably thicker than the oceanic plates
What are three types of convergent boundaries?
Oceanic-continental convergence: Oceanic plates sink beneath continental plates, creating subduction zones and mountain ranges. Oceanic-oceanic convergence: When two oceanic plates collide, one plate is subducted beneath the other, leading to trench formation and volcanic island arcs. Continental-continental convergence: Two continental plates collide, resulting in the uplift of crust and the formation of mountain ranges.
What plates meet in subductive zones?
Oceanic plates typically subduct beneath continental plates or other oceanic plates at subduction zones. The denser oceanic plate is forced beneath the less dense continental plate, leading to the formation of features such as deep ocean trenches, volcanic arcs, and earthquakes.
What oceanic landform is most likely to be found where two plates are moving away from each other?
Rift Zone
Which landform is likely to form where two oceanic plates push together?
A deep ocean trench is likely to form where two oceanic plates push together in a convergent boundary. This is because one of the plates subducts beneath the other, creating a deep trench.
What is oceanic plates?
Oceanic plates are sections of the Earth's lithosphere that are found beneath the oceans. These plates are denser and thinner than continental plates and are typically composed of basaltic rock. Oceanic plates are constantly moving due to the process of plate tectonics, where they can collide with, slide past, or be forced beneath other plates.
When oceanic plates come together what land form does this event create?
When oceanic plates come together, they create a subduction zone where one plate is forced beneath the other. This process forms deep ocean trenches and can lead to the formation of volcanic arcs and islands.

Are oceanic plates measured in seismic waves?
No, oceanic plates are not measured directly in seismic waves. Seismic waves are used to study the behavior of tectonic plates, including oceanic plates, by analyzing how they interact with each other and the Earth's interior. Measurements of oceanic plates involve techniques like satellite mapping, bathymetry, and GPS data to track their movement and deformation.
When two geologic plates are moving away from each other what happens?
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
Where do you find the mountain ranges with respect to the oceanic ridges?
Mountain ranges are typically found near convergent plate boundaries, where tectonic plates collide and push up the Earth's crust. Oceanic ridges, on the other hand, are located at divergent plate boundaries where tectonic plates move apart and create new oceanic crust. Mountain ranges are not usually found directly on top of oceanic ridges.
