Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do...
They can make build-ings fall down and set off landslides(山崩).A strong earthquake which occurs on the seafloor can push water upwards and createhuge waves called tsunamis.These waves can reach speeds of up to 500 kilometers an hour and destroy anything intheir path.So far scientists haven...
to keep the magma in place. 可以让岩浆保持在原位。 But when this equilibrium is thrown off, the consequences can be explosive. 但是当这种平衡被打破, 就有可能产生爆炸性的后果。 One of the most common causes of an eruption 火山喷发最常见的原因之一 is an increase in magmastatic pressure. 是...
forecast- n. statement about what you think is going to happen frequency- n. the fact or condition of happening often drought- n. a long period of time with little or no rain
Aftershocks are a sequence of quakes that happen after the larger "mainshock" on a fault. They tend to occur near the fault where the mainshock occurred and are part of the "readjustment process" after the main slip on the fault, the scientists at USGS say. ...
Causes of Natural Disasters The main causes of natural disasters are tectonic shifts, lunar activities, deforestation, soil erosion, air pressure, ocean currents, pollution, global warming, mining, seismic waves, etc. Agricultural practices, mining, deforestation, etc., can lead to landslides. Plants...
These enormous waves can also be produced by landslides. There is concern that a future massive landslide on an unstable part of the island of La Palma in the Canary Isles may trigger a huge tsunami that would travel westward across the Atlantic, causing devastation to the east coast of ...
Landslides and avalanches are themost dramatic, sudden, and dangerous examplesof earth materials moved by gravity. Landslides are sudden falls of rock, whereas avalanches are sudden falls of snow. Here is a video of a snow avalanche. What causes avalanche?
I don't know if it was snow or floods, or landslides. Or earthquakes.Or wildfires. Or any of the other things that happen in California.But the last time they had a real problem, they had a drain on power. And they said, by the way, if you have a new electric car, please do ...
What causes lightning in a volcanic ash cloud? Here is an idealized sequence of events that leads to lightning: Starting state (particles might have already been charged by some previous process). Collisions lead to charge separation. For this to happen there has to be some difference in the ...
