Granite forms long curved cracks known as "joints." These joints occur due to the cooling and contraction of the rock as it solidifies from molten magma. The process allows for the development of natural fractures that can vary in size and shape.
Granite is formed from molten rock that has cooled. Since it forms underground, however, the molten rock that it forms from is called magma rather than lava.
No, granite does not form as a lava flow. Granite forms deep underground from the slow cooling of magma. Lava flows are composed of different types of igneous rocks, such as basalt or andesite, that form at the Earth's surface during volcanic eruptions.
Granite and basalt are made when magma cools. Granite forms from slow-cooling magma underneath the Earth's surface, while basalt forms from rapidly-cooling magma on the surface.
When put under pressure, granite can change into a metamorphic rock called gneiss. Gneiss forms from the re-crystallization of granite under high temperatures and pressures, resulting in a distinctive banded appearance and different mineral composition.

No. Granite forms underground in the crust. If granitic magma reaches the surface and cools it forms a rock called rhyolite.
This line is called the meniscus.

A fissure.
Ice wedging is a form of mechanical weathering.
No, granite forms deep within the Earth's crust from the slow cooling of magma. It is an intrusive igneous rock, meaning it forms below the surface.

The radius of the sphere of which a lens surface or curved mirror forms a part is called the radius of curvature.
When granite melts within the Earth, an extrusive rock called rhyolite forms upon eruption at the surface. Rhyolite is the equivalent extrusive rock to granite and has a similar composition, but it forms from the rapid cooling of magma at the surface rather than slowly solidifying beneath the Earth's surface.
Silica is found in the upper mantle, but not granite. Most of the minerals in the mantle are silicates, meaning they contain silica. Granite is found in the crust, primarily conditnental crust, as it forms from high-silica magma. The upper mantle is composed mostly of a lower-silica rock called peridotite.
