Global warming refers to the rise in average surface temperatures on Earth since the 1950s due to greenhouse gas emissions from human activities. The global surface temperature has increased by about 0.74°C over the past century and is projected to rise another 1.1-6.4°C by 2100 if emissions continue at a high rate. This warming is causing sea level rise and changes in weather patterns, and is expected to have widespread effects on natural and human systems. However, there is ongoing political debate around efforts to reduce greenhouse gases and mitigate global warming.
Solar prominences are huge loops of solar material that extend outward from the sun's surface. They can be several miles wide and tall. Prominences form over timescales of about a day and contain cooler plasma than the corona, appearing as bright features against the dark sky. The largest prominence observed was over 350,000 km long. Prominences are anchored in the photosphere by magnetic fields and supported against gravity, existing at boundaries between magnetic polarities. They can persist in the corona for several months before erupting.
This presentation is about landslide and i prepared this to know about the knowledge of landslide and how to do during landslide for safe. I hope to see your comments.
This document provides an overview of landslides, including their causes, types, and historical examples. It begins by defining a landslide as a geological phenomenon where gravity causes ground movement such as rock falls and slope failures. Landslides can be triggered naturally by factors like heavy rain, earthquakes, and erosion, or anthropogenically by deforestation, construction, and blasting. The document then describes several types of landslides including debris flows, earth flows, debris avalanches, sturzstroms, and shallow landslides. Historical examples from the 19th-21st centuries are also mentioned.
