How do Tsunamis change Earths surface? by Sarah Miller - Prezi
WebMar 28, 2024 · Most tsunamis are generated by earthquakes with magnitudes over 7.0 that occur under or very near the ocean and less than 100 kilometers (62 miles) below Earth's surface (earthquakes deeper than this are unlikely to displace the ocean floor). Generally, an earthquake must exceed magnitude 8.0 to generate a dangerous distant tsunami. WebAt the surface, currents are mainly driven by four factors—wind, the Sun’s radiation, gravity, and Earth’s rotation. All of these factors are interconnected. The Sun’s radiation creates prevailing wind patterns, which push ocean water to bunch in hills and valleys. csm.edu

WebMay 18, 2024 · Tsunami or tidal waves are a series of water waves that are caused when the sea bed or sea floor moves vertically upwards in an earthquake. Tsunamis have the potential to wipe out half a city in minutes. Tsunamis are also known as tidal waves and are a grave hazard to many parts of the world. WebMar 7, 2012 · The massive 9.0 magnitude earthquake and tsunami that devastated Japan on March 11, 2011 also impacted Earth's gravity field, the length of its day and shattered icebergs a world away in Antarctica. WebEarth’s spin, tilt, and orbit affect the amount of solar energy received by any particular region of the globe, depending on latitude, time of day, and time of year. Small changes in the angle of Earth’s tilt and the shape of its orbit around the Sun cause changes in climate over a span of 10,000 to 100,000 years, and are not causing climate change today. eaglesgreenday
