The Earth's plates moved over millions of years, bringing continents and other features of the Earth to their present arrangement. This movement of the lithosphere is explained by The Theory of Plate Tectonics.
Give a brief account on The Theory of Plate Tectonics.The widely accepted scientific theory known as plate tectonics states that the Earth's lithosphere is composed of numerous large tectonic plates that have been moving gradually for close to 3.4 billion years. The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.
The solid outermost shell of the planet, known as the lithosphere, is divided into seven or eight major plates and a large number of smaller plates, or "platelets," on Earth. The direction of the plates' relative motion determines the kind of plate boundary—convergent, divergent, or transform—at which they converge. Earthquakes, volcanic eruptions, mountain-building, and the formation of oceanic trenches occur along these plate boundaries (or faults). Every year, the relative movement of the plates typically fluctuates between 0 and 10 cm.

Explanation:
use the mlc map document (it shows all the typical components of a mid-latitude cyclone: the l, fronts, isobars), and your lecture notes and diagrams from meteorology lectures 6 through 13 to answer the questions below.
A mid-latitude cyclone develops more specifically when an upper-level disturbance crosses over a stationary front at the surface, weakening the area of low pressure along it as divergence aloft lessens the weight of the local air columns.
The dynamic interaction of warm tropical and cold polar air masses near the polar front leads to mid-latitude cyclones. The warm air is cyclically lifted vertically into the atmosphere as a result of this interaction, where it combines with colder upper atmosphere air. On satellite images, mid-latitude cyclones can be recognized by their "comma" shape. Figure A shows the "Storm of the Century" in 1993. (Photo credit: NOAA) Just with other low pressure systems, mid-latitude cyclones develop from the divergence of air high in the atmosphere. According to the Norwegian model, commonly referred to as the polar front theory, cyclones have a six-stage life cycle that is generally predictable. Located in the middle latitudes (i.e., 30 N to 55 N), the mid-latitude cyclone is a synoptic scale low atmosphere system with cyclonic (counter-clockwise in the northern hemisphere) flow.

Underground coal mining is more dangerous and labor extensive compared to _____ mining, so it is also more expensive
Underground coal mining is more dangerous and labor extensive compared to strip mining, so it is also more expensive.
The process of removing coal from the earth is known as mining. Because of its high energy content, coal has been utilized extensively to produce electricity since the 1880s. Coal is used as a fuel in the steel and cement industries to extract iron from iron ore and to make cement.
Environmental concerns have become more significant since 1970, including the health of workers, the degradation of the environment caused by strip mining and mountaintop removal, air pollution, and the impact of coal burning on global warming. By removing the ground above each coal seam, strip mining exposes the coal. The earth that has to be removed is known as "overburden" and is taken out in broad strips.

the major process controlling the transfer of carbon from the atmosphere into the geosphere (rocks and minerals)
Limestone production and chemical weathering of calcium silicate rocks are the major processes governing carbon transfer into geosphere (rocks and minerals) from the atmosphere.
How carbon is transferred from atmosphere to geosphere?Rain is the first step in the transfer of carbon from the atmosphere to the geosphere (rocks and minerals). Carbonic acid, a weak acid created when atmospheric carbon and water interact, is released into the atmosphere as rain. In a process known as chemical weathering, the acid degrades calcium silicate rocks and releases calcium. The calcium released in this manner reacts with the atmospheric carbon di oxide and form calcium carbonate (Lime stone).

Explain what it means to say that both the atmosphere and forests are carbon reservoirs.
The carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. The forests are cut down and burned as a fuel the and the carbon is released back to atmosphere. When new trees grow they use and store the carbon in the trunks. And process continues.
The “carbon cycle” refers to the constant movement of carbon from the land and water through the atmosphere and living organisms. This cycle is fundamental to life on Earth. Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs. The movement of carbon from reservoir to reservoir is known as the carbon cycle.
Forests are a vital part of the carbon cycle, both storing and releasing this essential element in a dynamic process of growth, decay, disturbance and renewal. At a global scale, forests help maintain Earth’s carbon balance.
Earth’s carbon balance is calculated as the carbon emissions from human activities minus the carbon uptake by oceans and land systems. Since the industrial use of fossil fuels began, the net carbon balance has resulted in increases in the atmospheric CO2 concentration from 280 parts per million to over 390 parts per million.
A forest is considered to be a carbon sink if it absorbs more carbon from the atmosphere than it releases. Carbon is absorbed from the atmosphere through photosynthesis. It then becomes deposited in forest biomass (that is, trunks, branches, roots and leaves), in dead organic matter (litter and dead wood) and in soils. This process of carbon absorption and deposition is known as carbon sequestration.
Carbon can be stored in a variety of reservoirs, including plants and animals, which is why they are considered carbon life forms. Carbon is used by plants to build leaves and stems, which are then digested by animals and used for cellular growth. In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. It is also stored in oceans, captured by many types of marine organisms. Some organisms, such as clams or coral, use the carbon to form shells and skeletons. Most of the carbon on the planet is contained within rocks, minerals, and other sediment buried beneath the surface of the planet.
The carbon cycle is vital to life on Earth. Nature tends to keep carbon levels balanced, meaning that the amount of carbon naturally released from reservoirs is equal to the amount that is naturally absorbed by reservoirs. Maintaining this carbon balance allows the planet to remain hospitable for life. Scientists believe that humans have upset this balance by burning fossil fuels, which has added more carbon to the atmosphere than usual and led to climate change and global warming.

This form of landforms occurs where a river enters an ocean, sea, estuary, lake, reservoir or another river that cannot carry away the supplied sediment.

Causes and effects of the invention of magnetic reversalScientists don't really know what causes magnetic field reversals, though they have duplicated the phenomenon in laboratory experiments with liquid metals, which would also spontaneously change the direction of their magnetic fields. Some theorists believe that magnetic field reversals could be caused by real events, such as the collision of tectonic plates or the impact of a large meteor or asteroid, but this theory is discounted by others. It is known that leading up to a magnetic reversal, the field strength decreases, and since our current magnetic field strength is now in steady decline, some scientists believe we will see another magnetic reversal in about 2,000 years.
If, as some scientists have suggested, there was a period in which there was no magnetic field at all before the reversal occurred, the effect on the planet is not well understood.
Some theorists suggest that having no magnetic field would expose the Earth's surface to harmful solar radiation that could potentially cause the global extinction of life. However, there are currently no demonstrable statistical correlations in the fossil record to verify this. The last reversal occurred around 780,000 years ago, and there is no evidence to suggest that there was a mass species extinction at that time. Other scientists argue that the magnetic field does not dissipate during a reversal, but only grows weaker temporarily.
