Marine fossils found at a mountain top
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.
The Adirondack Mountains in northern New York state show evidence of dominant crustal uplift over erosional forces. The mountains are composed of ancient rocks that have been uplifted and not significantly eroded, preserving their original structure. The large-scale faulting and igneous intrusions in the region also indicate tectonic activity and uplift processes.
The best evidence of crustal movement is seismic activity, where earthquakes occur due to the shifting of tectonic plates underneath the Earth's surface. Geological features like mountains, rift valleys, and ocean trenches also provide evidence of crustal movement over long periods of time. Additionally, the alignment of magnetic minerals in rocks recording the past movements of the Earth's magnetic poles is another indicator of crustal movement.
Both weathering and uplift are processes that contribute to the shaping of Earth's surface. Weathering breaks down rocks and minerals at or near the surface, while uplift refers to the movement of Earth's crustal materials upwards. Both processes are important in the formation of landscapes and the overall geologic evolution of the Earth.
Major mountain ranges are formed when crustal plates collide. The intense pressure and forces generated by the collision force the Earth's crust to buckle and uplift, forming mountain ranges.

Worldwide, the mountains are the evidence of crustal plates.
it is concept of earths crust is gravitational balance or equilibrium.
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.
