Which is stronger magnitude or intensity?
Regional SpecificsMagnitude and Intensity measure different characteristics of earthquakes. Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Which is higher magnitude or intensity? Magnitude is a measure of earthquake size and remains
How are neritic sediments different from pelagic sediments?
Natural EnvironmentsNeritic sediments cover about ¼ of sea floor and are near landmasses. The term pelagic means “of or relating to the open sea” particularly the upper layers of the ocean away from shore. Pelagic sediments are generally deep-water deposits mostly oozes (see below) and windblown clays. What is the difference between neritic and pelagic deposits

What are the effects of rockfall?
Natural EnvironmentsRockfall causes extraordinary amounts of monetary damage and death, the former mostly by impeded transportation and commerce due to blocked highways and waterways and the latter as direct casualties from falling rocks. What is formed as a result of a rockfall? What is formed as a result of a rockfall? A talus slope. A talus
What would happen if crater lake erupted?
Regional SpecificsThe largest explosions could produce pyroclastic surges, hot, rapidly moving clouds of gas and ash, which could move out a few miles from vents along the margin of the lake. Eruptions in deeper water are less likely to be explosive or affect areas around the rim. Is Crater Lake still an active volcano? Although considered
