Uplift occurs when tectonic forces push rock layers upward, leading to the elevation of land. This can happen at convergent boundaries, where tectonic plates collide. Subsidence occurs when the ground sinks or collapses, often due to factors like sediment compaction, mining activities, or the withdrawal of groundwater.

Which type of geologic event has to occur to create an angular unconformity?
An angular unconformity is formed when older tilted or folded rock layers are eroded, creating a flat surface, and then new horizontal layers are deposited on top. This type of geologic event typically involves periods of uplift, tilting, and erosion followed by subsidence and deposition.
Primary coasts are created by what processes?
Primary coasts are formed by natural processes such as volcanic activity, tectonic forces leading to uplift or subsidence, and deposition of sediment by rivers or glaciers. These coasts tend to have rugged landscapes and are directly influenced by geological forces.
Rising of regions of earth crust to higher elevations?
The rising of regions of Earth's crust to higher elevations is known as uplift. This can occur due to tectonic forces such as mountain building or volcanic activity, or through processes like isostatic rebound. Uplift can lead to the creation of features like mountains, plateaus, and raised coastlines.
What are the differences between subsidence sinkholes and collapse sinkholes?
subsidence sinkholes are different from collapse sinkholes in two ways . first,subsidence sinkholes ocer when there is almost no overburn,or material,above the limestone. collapse sinkholes happen when there is thick overburn. secondly, subsidence sinkholes occur slowly, over time, while collapse foms quckly beacause of human activity , such as well drilling.
What forces control the shape of Continental slope?
The shape of the continental slope is primarily controlled by gravitational forces, erosion by currents and waves, and tectonic processes such as subsidence and uplift. These forces work together to shape the steep boundary between the continental shelf and the deep ocean floor.
What is the difference between uplift and subsidence?
Uplift is when things like mountains, hills, and, plateaus are created. Subsidence is the opposite of thins, like when sink holes and valleys are made.

What is movement of material in vertical direction?
Uplift, if rising; subsidence, if lowering.

A result of epeirogeny is?
Uplift and subsidence of large land masses without significant deformation.
Is Epeirogeny a crustal uplift without deformation. True or False?
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.
What is assess the statement Isostasy never stops causing upift and subsidence.?
The statement "Isostasy never stops causing uplift and subsidence" reflects the ongoing nature of isostatic adjustments in the Earth's crust. Isostasy refers to the gravitational equilibrium between the Earth's lithosphere and asthenosphere, where changes in surface load—such as erosion, sediment deposition, or glacial melting—can lead to vertical movements of the crust. These adjustments can occur over geological timescales, meaning that while they are continuous processes, the rates and effects can vary significantly. Therefore, while isostasy is a constant process, the extent and impact of uplift and subsidence can fluctuate based on environmental and geological conditions.
What is subsidence inversion?
Subsidence inversion is a meteorological term. They occur when a large mass of warm air enters an area trapping cooler air beneath.
How subsidence occur?
Subsidence occurs when one plate is denser than the plate it is moving into. It then slips under the less dense plate and melts into the mantle.
Where do uplift occur at?
Uplift can occur at tectonic plate boundaries, where plates collide and push against each other. It can also occur in areas of volcanic activity, as magma rises to the surface and pushes up the overlying rocks. Additionally, erosion can cause uplift as weight is removed from the Earth's surface, allowing the underlying rocks to rebound upwards.
