When hot lava meets the cooler temperatures of the ocean, an instantaneous cooling reaction takes place within the hot lava causing the minerals to form and crystallize quickly, usually of a different chemical and molecular composition if it were allowed to cool gradually at the earth's surface. Also, the hot lava may take on saline water from the ocean, therefore altering the overall mineral composition.

Does igneous rock come from mountains?
Igneous rock is formed from the cooling and solidification of magma and lava. Volcanic mountains and underwater mid-ocean mountain ridges would contain igneous rock, as well as uplifted igneous intrusions.
How are Igneous and Sedimentary rocks like the Earth?
Igneous rocks are like Earth's inner core and mantle because they form from molten rock beneath the surface, while sedimentary rocks are like Earth's surface layers because they are made up of accumulated particles and sediments.
What is the most common igneous rock of the ocean basins?
Ocean basins are primarily made of the igneous rock, basalt.
What is the ocean of molten rock on which the continents float called?
The ocean of molten rock beneath Earth's crust is called the mantle. The movement of the molten rock in the mantle is responsible for driving the motion of tectonic plates, which are like giant puzzle pieces that make up Earth's surface.
What is the comparison between the igneous rock found near the mid-ocean ridge and the igneous rock found farther away from the mid-ocean ridge?
Igneous rock is formed through the cooling and solidification of magma or lava. Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling.
What is the color and type of rock that forms oceanic crust at mid-ocean ridges?
The color of the rock that forms oceanic crust at mid-ocean ridges is dark gray to black. The rock is primarily basalt, which is a type of igneous rock formed from the solidification of molten lava.
What are molten rocks?
There are three types of rock - igneous, sedimentary and metamorphic. Igneous rocks formed directly from magma (molten rock flowing under ground) or lava (molten rock flowing above the crust). Granite is an example of what forms as magma cools slowly over a very long time, and obsidian forms when lava cools quickly, such as from contact with ocean water.
Does igneous rock come from mountains?
Igneous rock is formed from the cooling and solidification of magma and lava. Volcanic mountains and underwater mid-ocean mountain ridges would contain igneous rock, as well as uplifted igneous intrusions.
How are Igneous and Sedimentary rocks like the Earth?

Why were the first rocks on earth most likely igneous?
In the beginning (starting 4.567 Ga), Earth's surface consisted of what is called a "magma ocean"; i.e. there was no crust, yet. The first rocks formed throuh cooling of this magma ocean at least 4.4 Ga (possibly earlier). Hence, they are igneous since they formed through cooling of magma. The hydrosphere (oceans, rivers, etc.) and consequently sedimentation and formation of sedimentary rocks came later.
Which hemispheres in which the Pacific Ocean lies?
The Pacific Ocean is actually located in parts of all four of the hemispheres of Earth. The ocean reaches from Asia and Australia in the west to North and South America in the east. To the north the ocean reaches the Arctic and in the south it reaches the Southern Ocean.
When ocean water reaches the poles what happens?
When ocean water reaches the poles, it cools down and becomes denser, causing it to sink to deeper parts of the ocean. This cold, dense water then starts to circulate and move towards lower latitudes, influencing global ocean currents and climate patterns. Additionally, the melting of ice at the poles adds freshwater to the ocean, impacting salinity levels and ocean circulation dynamics.
What rocks are located at mid ocean ridges?
Igneous.
What happens to energy from the ocean when it reaches the shore?
Some of it returns to the sea as it rolls back, some is converted to the displacment of air and some of it is converted into erossion
Can you get pregnant in the ocean with penetration?
Ofcourse you can.. if the sperm reaches it reaches. nuff said.
Name the hemispheres in which the Pacific Ocean lies?
The Pacific Ocean is actually located in parts of all four of the hemispheres of Earth. The ocean reaches from Asia and Australia in the west to North and South America in the east. To the north the ocean reaches the Arctic and in the south it reaches the Southern Ocean.
Is igneous rock close to or far from mid ocean ridges?
Igneous rock could appear anywhere on Earth.
