Well really the valleys BETWEEN hills form by glacial and/or other erosion. The hills are what's left behind.

Arêtes can form in two ways. They can form when two glaciers erode parallel U-shaped valleys, or they can form when two glacial cirques erode headwards toward one another, although frequently this results in a saddle-shaped pass, called a col.
Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
Glacial erosion is the process by which a glacial flows over the land, picking up rocks. Glacial deposition is the process by which a glacier gathers a huge amount of rock and soil as it Erodes the land in the path
Glacial drift
"Moraine" hills,...caused by glacial deposits while receding.
Drumlins and eskers are found in glacial areas. Drumlins are hills made of glacial sediment and till, while eskers are long ridges of glacial drift.

drumlins
The glacial features that occur in swarms of long and smooth canoe-shaped hills are called drumlins. Drumlins are typically formed under moving glaciers and indicate the direction of ice flow. They are important indicators of past glacial activity and can be found in large numbers clustered together in areas that were once covered by ice sheets.
The word erosion is a noun. The plural form is erosions.
Antral erosions of the stomach refer to erosions or ulcers that specifically occur in the antrum, which is the lower part of the stomach near the pylorus. These erosions can be caused by factors such as infection with H. pylori bacteria, excessive use of nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol consumption, stress, or smoking. Symptoms may include abdominal pain, bloating, nausea, or vomiting. Treatment typically involves addressing the underlying cause and medications like proton pump inhibitors to reduce stomach acid.
Eskers
Conical hills are the remains/remnants of a limestone surface and all are usually the same height above sea level
No
Stream erosions are things that can relate to normal erosions
