Interior pressure of the forces the magma through the crack. This upwelling of magma then rapidly cools and becomes brittle as it hardens. The pressure of the subsurface magma then breaks this brittle rock and forces more magma up in a continuous cycle.
What else can I help you with?
Ocean ridges are formed by what boundaries?
Divergent boundaries form ocean ridges.
What processes at a divergent boundary will help form the following rocks?
The process of upwelling magma is found a divergent boundaries. As this magma nears the surface it decompresses, and some of it flows onto the surface of the Earth as lava. Magma that solidifies beneath the surface of the Earth hardens into gabbro while lava on the surface of the Earth hardens into basalt. Both of these are igneous rocks. Metamorphic rocks are formed from the heat flowing from the igneous rocks. Sedimentary rocks are formed from the sediments collecting in the basins created from rifting (that is, the divergent boundaries). Metamorphic and sedimentary rocks are not considered to be formed at divergent boundaries.

What kind of magma is formed at divergent boundaries?
Usually a dense basaltic magma with low water content.
What boundary is formed when magma rises to the surface and new crust is formed?
A divergent boundary is formed when magma rises to the surface and new crust is formed. This process occurs at mid-ocean ridges where tectonic plates move away from each other, allowing magma to fill the gap and solidify into new oceanic crust.
Types of landforms formed by divergent boundaries?
Divergent boundaries can create landforms such as rift valleys, mid-ocean ridges, and volcanoes. Rift valleys are formed on continents when tectonic plates pull apart, creating long, narrow valleys. Mid-ocean ridges are underwater mountain ranges that form when new oceanic crust is created as plates move apart. Volcanoes can also form along divergent boundaries as magma rises to the surface through the newly formed crust.
What plate boundary are volcanoes formed at?
Volcanoes can form at three places-1. Divergent boundaries2. Convergent boundaries (oceanic-oceanic and oceanic-continental)2. Above hot spots
Plates move apart at what boundary?
divergent
Where are the majority of volcanoes formed and why are they formed there?
The majority of volcanoes are formed along tectonic plate boundaries, particularly at divergent and convergent boundaries. At divergent boundaries, tectonic plates pull apart, allowing magma to rise and create new crust. At convergent boundaries, one plate subducts beneath another, leading to melting and the formation of magma, which can result in explosive volcanic activity. These geological processes are driven by the movement of the Earth's tectonic plates and the heat from the mantle.
How plates move at divergent boundaries?
Plates are moved at a divergent boundary by the magma pushing upwards.
Are divergent boundaries where new crust is formed?
Yes, divergent boundaries are where tectonic plates move away from each other. As they separate, magma from below the Earth's surface rises to fill the gap, solidifying into new crust. This process is known as seafloor spreading when it occurs underwater, creating new oceanic crust.
