“Five of the Solomon Islands disappeared” due to sea level rise, how is this possible so quickly?
Earth ScienceAsked by: Chris Norton What happens to islands when sea levels rise? As sea level rises, island nations are at increased risk of losing coastal arable land to degradation as well as salination. Once the limited available soil on these islands becomes salinated, it becomes very difficult to produce subsistence crops such as breadfruit. How

What is the tectonic explanation for parallel ridges in the Arctic Ocean?
Earth ScienceAsked by: Dallas Dooley Is the Arctic Ocean a divergent ocean? The Arctic Ocean is home to the volcanically active Gakkel ridge, which is an example of a divergent plate boundary. Unlike volcanic activity on land (tall, conical, non-spreading), undersea volcanoes are linear, usually long and continuously oozing magma. What formed the Lomonosov Ridge? The
What is this geographical feature? (as seen in maps)
Earth ScienceAsked by: Samuel Lotz What is a geographical feature on a map? Geographic features, or geographical formations, are components of a planet that can be referred to as locations, sites, areas, or regions (and therefore may show up on maps). There are natural geographic features, abstract geographic features, and on Earth there are also artificial
