Tectonic plates currently under the ocean that crash into each other and force the land upward creating a mountain that when it breaches the surface makes an island. The more likely scenario is volcanic activity that builds up land from lava flowing out and hardening as its cooled by the water and layering up till it makes an island.
What else can I help you with?
What creates a new volcano?
the flow of lava, cooling off and solidifying on the Earth's surface creates a new volcano
Why are mountains cunstructive?
The building of mountains creates new land on the surface of the Earth.
What would most likely be responsible for creating a new island on the surface of the earth?
Waves
Are Earthquakes and volcanoes are important for the formation of island chains?
Yes, earthquakes and volcanoes are important for the formation of island chains. Volcanic activity creates new land through the eruption of lava and ash, leading to the formation of islands. Earthquakes are also generated by the movement of tectonic plates beneath the Earth's surface, which can contribute to the formation and shaping of island chains.
Why is the surface of mercury covered with meteor impact craters while earth surface has relatively few craters?
Earth is a geologically active planet, the heat in its core moves the Earth's surface around and creates new oceans and mountains over time and these are eroded slowly by the processes going on in and caused by Earth's atmosphere. On Mercury there is no atmosphere and the planet no longer has a hot core causing its surface to be reworked, Thus the craters made in Earth's surface are erased over time while those on Mercury are not.
What boundary creates seafloor spreading?
A divergent boundary creates seafloor spreading. At these boundaries, tectonic plates move apart, allowing magma to rise from below the Earth's surface and create new crust at the mid-ocean ridges.
The hawaiian island formed over a?
The Hawaiian Islands formed over a volcanic hotspot in the Earth's mantle, where magma rises to the surface through the Pacific Plate. As the tectonic plate moves over the hotspot, it creates a chain of volcanic islands, with the oldest island in the chain eroding away as new islands form. This process has been ongoing for millions of years, leading to the formation of the Hawaiian Island chain.
What forms a new rock on earth surface?
Lava.
How does magma change the earth surface?
When magma erupts on to the earth's surface it hardens and forms new land.It depends on if your talking about magma or lava, lava is on the surface of the Earth and magma is inside (underground).
What is the Earth's second largest island?
Papau New Guinea
In the prosess of sea-floor spreading. what happens when magma rises to earth's surface and solidifies?
It creates new seafloor and moves the oceanic plate like a conveyer belt toward a subduction zone where it re-enters the mantle.
Name two ways that a volcano can change the Earths surface quickly?
Volcanoes can change the Earth's surface quickly by producing lava flows that can cover large areas in a short time, creating new landforms. They can also trigger landslides and lahars (mudflows) that rapidly reshape the landscape.
