For This Discussionplease Choose 2 Terms From This Listglacier Terms For this discussion: Please choose 2 terms from this list: Glacier terms revised. docx. To ensure that we have some variety, one of the terms you choose should start with a letter close to the first letter of your last name. Find a good picture or video to illustrate each of your terms (2 total pictures and/or videos). Define what each term means. You should use the definition from your textbook or a reputable source such as the USGS Glossary of Glacial Terminology. You may also use Wikipedia for this assignment. Continue your post by explaining more about the feature in your own words, for example, how the feature is formed or how the process works, where it is found, its importance, or any other pertinent facts you find in your research. The goal is to provide interesting and accurate information to your fellow classmates, and it will also help you with test preparation since these are key terms from your text. Five or six sentences about each term should be enough. The descriptions can be brief but should also be well-written. Any direct quotes that you use should be clearly indicated as quotes. References are very important. Please give your references for everything: your pictures, definition, descriptions, and quotes. Use citefast.com to put your references in correct form. At citefast.com, choose APA style and fill in the information that you have reasonably available. 200 words is enough, but I only can give you 2-3 hours to complete.

Glaciers are massive bodies of ice that have accumulated over years or centuries and move slowly across land surfaces. For this discussion, I have chosen two terms: "glacier formation" and "ice calving." These terms provide insight into how glaciers develop and the dynamic processes associated with their movement and melting. 1. Glacier Formation According to the USGS Glossary of Glacial Terminology, glacier formation begins with snowfall accumulating in a specific area over time, exceeding the amount that melts during the summer months. As snow builds up, it compresses under its own weight, transforming into firn, an intermediate form between snow and glacial ice. Over decades or centuries, the pressure causes the firn to recrystallize into dense, solid ice, forming a glacier. Typically, glaciers are found in polar regions and high mountain environments where temperatures remain cold enough year-round. The process of glacier formation is crucial in shaping Earth's landscape, carving valleys and creating landforms like fjords and cirques. Glaciers act as freshwater reservoirs and influence global climate patterns through their reflective surfaces, which reflect sunlight and regulate temperature. 2. Ice Calving Ice calving refers to the process where chunks of ice break off from the edge of a glacier or ice shelf, often falling into the ocean. This process occurs when the glacier's frontal part becomes overextended or destabilized, often due to melting or warm ocean currents undermining its structure. As the ice reaches a point of structural failure, large blocks detach, creating icebergs. Calving is a natural part of a glacier's lifecycle but can be accelerated by climate change, leading to faster glacier retreat. It is most commonly observed in polar regions and along the edges of ice shelves. The process significantly contributes to sea level rise as the released ice melts into the water, adding to global sea volumes. Understanding calving helps scientists predict
