Why might a laccolith be detected at earths surface before being exposed by erosion?
A laccolith may be detected at Earth's surface before being exposed by erosion because it causes uplift in the overlying rocks, creating a dome-like structure. This uplift can be visible through topographic mapping or geophysical surveys before the laccolith is fully exposed by erosion processes. Additionally, the resistant nature of the igneous rock forming the laccolith may also prevent erosion, keeping it buried beneath the surface for an extended period.

What is the igneous intrusion similar to but larger than a laccolith?
A batholith is a large igneous intrusion that is similar to a laccolith but much larger in size. It is typically formed from the cooling and solidification of magma deep below the Earth's surface and covers a larger area compared to a laccolith. Batholiths are commonly associated with mountain ranges and are often exposed through erosion.
How might the surface landscape above a laccolith look?
The surface landscape above a laccolith typically appears as a dome or bulge due to the intrusion of magma creating a blister-like formation beneath the Earth's crust. Over time, erosion may expose the laccolith's core, revealing the igneous rock that solidified underground. This can result in unique geological features like mesas or buttes.
What is an igneous intrusive feature that forms from a lens shaped mass of magma that arches over the overlying strata upwards?
A laccolith is an igneous intrusive feature that forms when a lens-shaped mass of magma intrudes between rock layers and arches the overlying strata upwards. As the magma cools and solidifies beneath the Earth's surface, it creates a domed structure that can be exposed through erosion, revealing a characteristic mushroom-like shape.
Dome-like mass of instrusive igneous rock?
A batholith is a dome-like mass of intrusive igneous rock that forms when magma solidifies beneath the Earth's surface. Batholiths are typically made of granitic rock and can cover large areas, often extending for hundreds of square kilometers. They are commonly associated with mountain-building processes and can be exposed at the surface after erosion.
Buried rock is exposed at earths surface by the combination of which two processes?
The combination of weathering and erosion exposes buried rock at the Earth's surface. Weathering breaks down the rock into smaller pieces, while erosion transports these pieces away, eventually revealing the rock at the surface.

Do laccolith features occur when volcano lava cools at the surface?
No. A laccolith is an intrusive feature.
What is the difference between a sill and a laccolith?
A sill is a horizontal sheet of igneous rock that is intruded between existing rock layers, while a laccolith is a dome-shaped intrusion that causes the overlying rock layers to arch upwards. Sills are flat and parallel to existing rock layers, while laccoliths are typically lens-shaped and create bulges in the rock layers above them.

Is granite below or above the surface?
Granite forms below the surface, but it can be found at the surface where it has been exposed by erosion or uplift.

Can coal be found on the surface?
Coal can be found in certain locations where it is exposed at the surface via erosion of the overburden. Most often, it is not.
What are processes that expose plutons to earth's surface?
Plutons can be exposed to Earth's surface as a result of uplift and erosion. ~Meag

What is it called when wind blows sand and silt against exposed rock eventually wearing the rock surface?
Erosion?
How can land can be polluted?
On the mining sources the surface is exposed to erosion which destroys the quality of the land.
