What type of rock is formed when the lava cools down?
cooled lava when it melts is turned to rock if you take a malet and pound it you can see the old lave ozz out into a gush so its like that to store regular lava so its fresh like a fruit you store it in the fridge and when ou open the fridge the fruit is fresh
Some of the oldest rocks ever found have been estimated to be about 3.5 billion years old. Is it likely that these rocks were present when Earth was first formed?
No, rock material is constantly recycled on Earth as rock is melted into magma.
How does the diagram show that new crust forms from molten materials?
because the new rock out and old rock goes down to mantle and it melt.
When old rocks are partially melted or squeezed what rocks are formed?
Metamorphic rocks
What two groups of rocks that form all 3 kinds of rocks?
In reality, every rock on Earth could be formed of ingredients from any of the three rock types: sedimentary, igneous, metamorphic. This is referred to as the rock cycle, the continuous, billions of years old process of rock recycling.As for the direct transformation of one rock type into another due to heat and pressure, only metamorphic rock can be created this way. The metamorphism can occur to existing sedimentary, igneous, and metamorphic rock.Igneous rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous. Sedimentary Rock can also be eroded into sediments, Ultimately becoming another Sedimentary rock. And it can also be metamorphosed by heat and pressure, becoming a Metamorphic Rock before being melted into Igneous. Metamorphic Rock can be eroded into sediments, Ultimately becoming Sedimentary rock. And it can also be metamorphosed farther by heat and pressure, becoming another type of Metamorphic Rock in the line before being melted into Igneous.

Can a rock be heated into an old rock?
It can be melted, but would form the same type of rock when it was cooled and hardened again, the structure depending on how it cooled and how fast.
Explain the process by which new sea floor forms at mid ocean ridges?
as it spread away from a mid-ocean ridge, the sea floor carries with it a record or magnetic reversals. i hope this answer would be correct :) also, when the magma rises through fractures in the sea floor at the mid-ocean ridge, the magma cools and forms new rocks. this new rock takes place of the old rock and the old rock gets pulled away.
The continuous process by which new rock forms from old rock materials is called the?
rock cycle
What is the continual process by which new rock forms from old rock is called?
It's called the rock cycle.
How do you chemically change a rock?
Metamorphism will alter the chemical molecules in a rock as it cools down, Otherwise, weathering will alter old molecules and create new ones.
What is the process by which new rock forms from old rocks?
There are several ways by which old rocks can become "new" rocks, all of which are described by the rock cycle. A rock, no matter what class it falls under, can become igneous, metamorphic, or sedimentary. When melted and then re-cooled, a rock become igneous. When exposed to very high temperature and pressure, the rock becomes metamorphic. When weather or eroded by wind, water, etc., and then lithified (cemented together), the rock becomes sedimentary. Again, any rock can go from one class to the other, or in some cases become a new rock of the same class.

How Did Rock get Its Name?
Rocks come from a cycle we call the rock cycle, it starts off as magma, as this cools, igneous rocks are made. Weathering and erosion causes igneous rocks to turn into sediments which forms into sedimentary through compaction. Heat and pressure causes sedimentary rocks to turn into metamorphic rocks which then gets melted back into magma. This goes in a circle which never ends, so rocks are being formed all the time.

What is the crust under the oceans made of?
The plates under the Earth are made of lots of types of rock(sedimentary metamorphic and igneous rock) but underneath is the Earths mantle, a liquid like mix of melted rock. I am not that old but am taking geography, sorry if this doesn't help but good luck ;)
How does the diagram show that new crust forms from molten materials?
because the new rock out and old rock goes down to mantle and it melt.
