Three ways humans contribute to slope instability
How do neap tides and spring tides differ, astronomically?
Spring tide: Earth, Moon and Sun are in alignment

How to beaches change from winter to summer?
Gentle waves in the summer deposit fine sand from offshore bars onto the beach, creating wide beaches
Harsh waves in the winter remove fine sand from the beach and carry it out to sea, shrinking the beach
The reason most of NH's productive aquifers are located in areas of glacial drift
Glaciers leave behind till, sand, and gravel which have high hydraulic conductivities
The erosional process by which a glacier removes a piece of bedrock by freezing in bedrock cracks
