Granite forms underground and may take millions of years to cool from a state of magma to a solid rock. Some granites are billions of years old, and some granite is forming as you read these words.
The granite would be older because it had to form first in order for the sandstone to contain pieces of it. The sandstone would have formed later on top of the granite layer.
Yes, granite forms from the slow cooling and solidification of magma deep within the Earth's crust. As the magma cools, minerals such as quartz, feldspar, and mica crystallize and combine to form granite. This process typically occurs over millions of years.
Granite does not directly transform into obsidian. Obsidian is formed when lava cools very quickly, without giving crystals a chance to form. Granite, on the other hand, forms deep beneath the Earth's surface through the slow cooling and solidification of magma. So, while both are igneous rocks, they form under different conditions.
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
No, granite forms from the slow cooling and solidification of molten rock beneath the Earth's surface. This process allows the minerals within the rock to crystallize and form the characteristic interlocking grain structure of granite.
Granite turns into Gniess.
Gneiss may form from either granite or schist.
Yes, granite is formed from cooling magma.
Our new countertops are made form granite.
No. Granite and basalt have different compositions and form under different circumstances.
In the volcano/magma chamber, different minerals that make up granite, (feldspar, quartz, etc.) mix to form grainy, large crystals of the different minerals. That is how granite is formed.
No, granite is not an ore mineral. Ores are the rock form of certain metals.

Granite is a form of rock.The ornament is made from granite.
Granite is the rock type/magma produced when one melts continental crust. It can also form by fractionation of more basaltic magmas.
Granite is the result of slow cooling processes of felsic magmas.
