Answers
6- There are two ways by which we can measure the strength of an earthquake: magnitude and intensity. Magnitude is proportional to the energy released by an earthquake at the focus. It is calculated from earthquakes recorded by an instrument called seismograph.. 11- The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface
7- Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. 5- earthquakes can't be predicted. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years. 1- The lithosphere is divided into separate "plates" that move relative to each other on the underlying, relatively weak asthenosphere in a process ultimately driven by the continuous loss of heat from the Earth's interior..It can also be said as tectonic plates..
