Type of wheathering and temperature in Antarctica
Antarctica experiences a type of weathering called freeze-thaw weathering, also known as frost weathering. This process occurs when water seeps into cracks or porous rock surfaces, and then freezes. As water freezes, it expands and puts pressure on the surrounding rock, causing it to fracture and break apart over time. This type of weathering is quite common in Antarctica due to its extremely cold temperatures.
Speaking of temperatures, Antarctica is the coldest place on Earth. The temperature in Antarctica varies depending on the time of the year and the specific location within the continent. On average, the temperatures during the Antarctic winter (June to August) range from -40°C (-40°F) to -70°C (-94°F). In some parts, temperatures can drop even lower, reaching -89.2°C (-128.6°F), which is the lowest temperature ever recorded on Earth.
During the summertime (December to February), the temperatures in Antarctica rise, although they still remain quite cold. On average, temperatures range from -10°C (14°F) to -30°C (-22°F), but can occasionally reach above freezing, especially near the coast.
It's important to note that the weather conditions in Antarctica can be harsh and unpredictable, with strong winds and extreme wind chill factors. The low temperatures and freezing conditions play a significant role in shaping the landscape of the continent through freeze-thaw weathering and other geological processes.
