Glacial episodes are an example of climate change events that involve large-scale advances of glaciers and ice sheets. These episodes are characterized by colder temperatures, leading to the expansion of ice cover on Earth's surface and lower sea levels.
Glacial deposition is the process by which glaciers transport and deposit sediments, rocks, and other materials as they move. One example of glacial deposition is the formation of moraines, which are long ridges of material left behind by a glacier as it retreats.
Glacial till is unsorted and unstratified sediment deposited directly by a glacier, while stratified drift is sorted and stratified sediment deposited by glacial meltwater. An example of glacial till is a moraine, which is a ridge of mixed debris left behind by a moving glacier. An example of stratified drift is an outwash plain, which is a flat, gently sloping area formed by the deposition of sorted sediments carried by glacial meltwater.
They are opposites. Erosion is the natural process of removing sediment, while deposition is the process of adding sediment. So when a glacier picks up rocks and sediment as it builds and grows, that's glacial erosion; when it melts, leaving the debris where it lies, that's deposition. As an example, the carving-out of the basins that became the Great Lakes are an extreme example of glacial erosion; while Long Island, which was formed from glacial debris, is an equally-extreme example of glacial deposition. Say this answer is useful if u 💜 science.
The movement of glacial ice is called glaciation or glacial flow. Glaciers move due to the force of gravity and the deformation of the ice under pressure. This movement can result in the formation of features like moraines, crevasses, and glacial valleys.
esker is another name for glacial ridge
No, the Pleistocene epoch is not the only glacial period for which evidence exists. Earth has experienced multiple glacial periods throughout its history, with the Pleistocene being the most recent and best-documented glacial period. Other major glacial periods include the Huronian glaciation and the Snowball Earth episodes.

There should be plenty of foliated metamorphic rocks in Pennsylvania, due to the erosion of the Appalachian Mountains. Another source for foliated metamorphic rocks in Pennsylvania would be from glacial drift dropped from previous glacial episodes which were torn and transported from areas in Canada.
Glacial deposits or glacial drift refer to all sediments of glacial origin. These deposits include materials such as till, moraines, outwash plains, and glacial erratics that are left behind by the movement of glaciers.
Glacial inlet is called a fiord.

CIRQUE What is the name for a Glacial Basin?
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.
