Glacial Carving is when huge chunks of ice in the glacier get broken off and washed away. This can only happen when the snout of the glacier meets water.
Glacial erosion produces U - shaped valleys.
Glacial spillways are formed when meltwater from a retreating glacier creates a pathway through moraines or other glacial deposits. As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.
The features that are not a result of a glacier carving out rock include sedimentary layers formed by water deposition, such as deltas or riverbanks. These formations are created by the accumulation of sediments transported by water rather than by glacial activity. Other non-glacial features might include volcanic formations or man-made structures, which are unrelated to the processes of glacial erosion and movement.
A feature that is not the result of a glacier carving out rock is a delta. Deltas are formed by the deposition of sediment carried by a river as it flows into a larger body of water, such as an ocean or lake, rather than through the erosive action of a glacier. In contrast, features like U-shaped valleys and glacial striations are directly caused by glacial movement and erosion.
Glacial erosion is caused by moving masses of ice. As glaciers flow over the land, they pick up rocks and debris, scraping and carving the land beneath them. This process shapes the landscape through processes such as plucking and abrasion.
The result of a glacier carving out rock as it moves is the formation of u-shaped valleys, jagged mountain peaks, and smooth rock surfaces. This process, known as glacial erosion, can create dramatic landscapes by scraping and plucking rocks along the glacier's path.
Glacial drift refers to the material deposited by glaciers as they advance and retreat. As glaciers move, they pick up rocks, sediment, and other debris, and when the glaciers melt, they leave behind this material known as glacial drift. This process of deposition and erosion by glaciers reshapes the landscape by carving out valleys, creating moraines, and smoothing out the land.
A glacial groove is a long, linear indentation or scratch in bedrock that is formed by the movement of a glacier. As the glacier flows over the rock surface, it picks up and carries rock debris, causing abrasion and carving grooves into the bedrock. These grooves provide evidence of past glacial activity and can help scientists understand the direction and extent of glacial movement.
D. Stratified drift is not the result of a glacier carving out rock as it moves. Instead, stratified drift refers to sediment that has been sorted and deposited by glacial meltwater, rather than being directly shaped or formed by the glacier's movement. In contrast, fjords, horn peaks, and U-shaped valleys are all features that result from glacial erosion.

During the last ice age, glaciers in Pennsylvania shaped the land by carving out valleys, smoothing out mountains, and depositing sediments. This glacial activity created the diverse landscape of Pennsylvania, including the formation of the Pocono Mountains and the famous valleys like the Delaware and Susquehanna. Today, evidence of glacial activity can be seen in the moraines, drumlins, and other glacial features throughout the state.
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.
