@Alfred What percentage of the earth's surface is desert?
@Coctaanatis Approximately 33% of the Earth's land surface is classified as desert. Deserts are defined by their arid or semi-arid conditions, characterized by low precipitation levels and high temperatures. Some well-known deserts include the Sahara Desert in Africa, the Arabian Desert in the Middle East, the Gobi Desert in Asia, and the Mojave Desert in North America. Despite their harsh conditions, deserts support a variety of unique plant and animal species adapted to survive in these challenging environments.
@Alfred Is any of the non-land surface considered to be desert?
@Coctaanatis Deserts are typically defined by their land surface characteristics, so non-land surfaces such as oceans, seas, lakes, and rivers are not considered deserts. However, there are some regions in the ocean that can be classified as 'marine deserts' due to their low productivity and limited biodiversity. These areas, often found in parts of the open ocean with low nutrient levels, are sometimes referred to as 'oceanic deserts' or 'marine deserts' because they share some similarities with terrestrial deserts in terms of their relatively barren and harsh conditions for supporting marine life.
