Giuseppe Mercalli is credited as the creator of the modified Mercalli intensity scale, sometimes known as the Mercalli scale.
The scale is employed to quantify earthquake damage. People waking up, furniture shifting, and objects becoming damaged are all important components of this scale. Because the scale is dependent on the witnesses, it is thought to be less effective in remote regions. The overall damages are rated on the Mercalli scale from I to XII.
Seismic waves are recorded by seismographs. The "size" or amplitude of the seismic waves produced by an earthquake source and detected by seismographs is a measure of an earthquake's magnitude. (The section on seismic waves describes the types and characteristics of these waves.) Due to the wide variation in earthquake size, a mathematical technique must be used to compress the range of wave amplitudes reported on seismograms for comparison.

Answer: Intrusive igneous rocks form at depths of several hundreds of metres to several tens of kilometres. Sediments are turned into sedimentary rocks only when they are buried by other sediments to depths in excess of several hundreds of metres. Most metamorphic rocks are formed at depths of kilometres to tens of kilometres. Weathering cannot even begin until these rocks are uplifted through various processes of mountain building—most of which are related to plate tectonics—and the overlying material has been eroded away and the rock is exposed as an outcrop.

which four factors are considered significant in causing the ice ages?
Four elements that are thought to have had a role in the Ice Age are variations in the tilt and orbit of the Earth around the Sun, variations in solar activity, atmospheric CO2 and methane concentrations, and the location of the continents.
Generally speaking, it is believed that ice ages are brought on by a series of positive feedback loops that are set off by periodic changes in the Earth's orbit around the Sun. When the orbital cycle turns back, these feedbacks which involve the spread of ice and the release of greenhouse gases work in reverse to warm the Earth once more.
An ice age begins when temperatures decrease and more water freezes into ice as a result of less sunshine reaching the northern latitudes. The northern latitudes receive more sunshine, which raises temperatures and causes ice sheets to melt.

how are the inner layers of the sun distinguished?
The deepest layer of the Sun that we can directly observe is called the photosphere. It extends to around 250 miles (400 km) above the visible surface at the core of the solar disk.
A layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface is known as the chromosphere (the photosphere). The chromosphere's temperature ranges from about 4000 K at the bottom (the so-called minimum) to 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C). As a result, in this layer (and higher layers), the temperature increases as you move further away from the Sun, as opposed to the lower layers, where the temperature increases as you move closer to the Sun's center.
Transition Region: Between the chromosphere and the corona, there is a quite small layer (60 miles/100 km) where temperatures suddenly increase from 8,000 to 500,000 K. (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
The Sun's corona, which begins at around 1300 miles (2100 km) above its surface, is its outermost layer (the photosphere). The corona has a temperature of 500,000 K (900,000 F, 500,000 C) or higher, possibly up to a few million K.

Should oil exploitation be banned in areas of natural beauty?
Yes, oil exploitation should be banned in areas of natural beauty.
Exploitation of natural resources is the use of natural resources for economic growth, sometimes with a negative result of conducting environmental degradation. Increasing population in world has compelled humans to exploit natural resources to meet economic needs or in economic growth.
History says that oil and gas development on public lands has damaged ecosystems, harmed species, and contaminated soil, air, and water. The construction of drilling facilities fragments public lands, displacing wildlife and destroying habitat, while oil spills, fires and other pollution can contaminate surface and ground water.
Roads built for drilling increase human activity in formerly undisturbed areas and can lead to increased poaching, litter, roadkill and human-caused fires; and they facilitate the spread of exotic species that replace native plants and animals. Most specifically, oil and gas development creates our dependency on fossil fuels, committing the people and their public lands to more greenhouse gas emissions and global warming.

what is wavelength?
Red light is more readily absorbed by water than other visible wavelengths and has a modest energy advantage over infrared light that cannot be seen. Due to this, red fish at a depth of 20 meters appear almost black. Compared to lower wavelength light, longer wavelength light is absorbed more quickly.
