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.

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.
How are Igneous and Sedimentary rocks like the Earth?
ignious comes from volcanoes molten lava and sedimentary comes from sand getting squezed together usually underwater (ocean, lake, etc.)
Where are the three types of rocks found?
Sedimentary rocks are found generally at the bottom of an ocean as this is where eroded material falls. Igneous rocks are found near volcanoes as they are molten rock. Metamorphic rock can be found anywhere, as it is formed in the ground and slowly comes up to the surface (but it is made of igneous or sedimentary rocks.)
Where is basalt when it cools?
It is in the ocean. It is also the cheapest igneous rock you can find in the ocean.
What is the ocean of molten rock on which the continents float called?
There is no ocean of molten rock underneath the continents. Tectonic plates, both oceanic and continental, move on top of the ductile asthenosphere.

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.

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.
Where is basalt when it cools?
It is in the ocean. It is also the cheapest igneous rock you can find in the ocean.
In sea-floor spreading what happens to the old oceanic crust as new molten material rises from the mantle?
It gets pushed out to either side of the mid-ocean ridge.

There is no ocean of molten rock underneath the continents. Tectonic plates, both oceanic and continental, move on top of the ductile asthenosphere.
Volcanic islands in the deep ocean are composed primarily of what igneous rock type?
Basaltic Igneous Rocks
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.
