They are formed under the earth's surface.
If the earth had a completely smooth surface and all the components form which it was made were all evenly mixed up, then the force of gravity would be the same at all points on its surface. However the earth is not smooth , it has mountains and hollows in its surface and the rocks form which it is made are not evenly mixed, some surface rocks are heavy (dense) and some are light. This means that as compared to the theoretical smooth earth gravity field, the real earth gravity field varies from point to point over the surface. A gravity survey measures the small variations in the pull of gravity over the earth's surface and makes a map of these changes. This map helps geologists understand where the dense and light rocks are beneath the surface.
igneous rocks
Igneous rocks are described as intrusive or extrusive based on formation. Intrusive rocks forms underneath the earth surface, while extrusive rocks forms on the surface of earth.
Water, ice, wind, acid, gravity, and temperature are all involved in the breaking down of rocks on the earth's surface.
Magma is under the surface of Earth's crust. Rocks on earth's surface are well ... on Earth's surface. Magma is also molten rock, not solid rock like the rocks on earth's surface.
igneous rocks that form on earth's surface
from earth surface ^_^
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
They are formed under the earth's surface.
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
Uplift replaces rocks on Earth's surface lost the process of erosion.

Weathering breaks down rocks on the Earth's surface by wind, rain, or ice.
Intrusive igneous rocks form from cooled magma below Earth's surface.
Apart form the Oceans the earths surface is made of rocks.
no sometimes it cools under earth's surface. that is called intrusive igneous rocks. when it reaches earth's surface and cools its called extrusive igneous rocks.
