True.
True. Epeirogeny refers to broad-scale vertical movements of the Earth's crust that occur without significant deformation or folding. It involves gradual uplift or subsidence of large regions over long periods of time.
There are three types of uplift: tectonic uplift caused by movement of tectonic plates, isostatic uplift due to changes in the earth's crustal thickness and density, and erosional uplift caused by erosion stripping away material and uplifting the remaining land.
Crustal shortening due to compression of the Earth's crust primarily results in reverse faults and thrust faults. In these types of faults, the hanging wall moves up relative to the footwall, leading to the stacking of rock layers and the formation of mountain ranges. This process is often associated with convergent tectonic plate boundaries, where plates collide, causing significant deformation and uplift of the crust.
One would expect to see the formation of mountains or hills as a result of the layer of the crust being pushed up. This process is known as crustal uplift, which can lead to the deformation and displacement of rocks, resulting in the creation of elevated landforms.
Yes, continental-continental collisions can lead to the formation of mountain ranges through the process of crustal uplift and folding. The intense pressure and deformation generated during the collision cause the Earth's crust to fold, creating large-scale mountain systems like the Himalayas.

Uplift and subsidence of large land masses without significant deformation.
epeirogeny
The best evidence of crustal uplift is the presence of elevated landforms such as mountains or plateaus. This uplift can result from tectonic forces or isostatic rebound following the melting of ice sheets. Geological features like tilted sedimentary layers or uplifted coastlines also indicate crustal uplift.
Epeirogeny refers to the slow, broad, vertical movements of the Earth's crust that can lead to the uplift or subsidence of large land areas. A result of epeirogeny is the formation of features like plateaus and basins, which can influence local climate and ecosystems. Additionally, these movements can affect sedimentation patterns and the distribution of natural resources over geological timescales.

Orogeny is a mountain building process while epeirogeny is a continent building process.2. In orogeny crust is severely deformed into into folds while in epeirogeny there may be simple deformation. 3. In orogeny the rock masses move in tangential direction to the earth's surface while in epeirogeny the rock masses move in radial or vertical direction to the earth's surface.
Any change in the volume or shape of Earth's crust is called crustal deformation. This can occur due to tectonic forces, such as compression, extension, or shearing, which lead to features like folding, faulting, and uplift.
There are three types of uplift: tectonic uplift caused by movement of tectonic plates, isostatic uplift due to changes in the earth's crustal thickness and density, and erosional uplift caused by erosion stripping away material and uplifting the remaining land.

The presence of marine fossils found high above sea level is a key indicator of crustal uplift. Additionally, the presence of erosional features such as river valleys in mountainous regions suggests uplift has occurred. Geological structures like fault blocks and folds also provide evidence of crustal uplift.
