A canyon is a deep, narrow valley with steep sides, often carved by a river or erosion. Canyons are typically formed over millions of years through the process of weathering and erosion.
Formation of Canyons
There are several ways canyons can form:
River Erosion:Rivers flowing through rock over long periods of time can carve out deep canyons, such as the Grand Canyon in the United States.
Glacial Erosion: Glaciers can carve out canyons as they move and melt, leaving behind steep-sided valleys.
Wind Erosion:Wind can erode rock and create canyons in arid regions, such as the famous Antelope Canyon in Arizona.
Steep Sides: Canyons have vertical or near-vertical walls that can be hundreds or even thousands of feet high.
Rock Formations: Canyons often showcase a variety of rock layers and formations, revealing the geological history of the area.
Wildlife and Vegetation: Despite the harsh conditions, many canyons support diverse ecosystems with unique plant and animal species.
Recreation and Tourism: Canyons are popular destinations for outdoor activities such as hiking, rock climbing, and sightseeing.

Observe seasonal patterns of sunrise and sunset to describe the relationship between the number of hours of daylight and the time of year (e.g., more hours of daylight during summer as compared to winter).
