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.

What makes a rock?A rock is a solid mass composed of geological materials. Individual mineral crystals, inorganic non-mineral solids such as glass, fragments of other rocks, and even fossils are examples of geological materials.
A mineral or mineral species is a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form in geology and mineralogy.
Igneous rocks form from molten rock deep within the Earth. Layers of sand, silt, dead plants, and animal skeletons combine to form sedimentary rocks. Metamorphic rocks are formed from other rocks that have been altered by underground heat and pressure.

Answer: what exactly are you sassing? Wat is your question ?
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.

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).

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.
Often, the size and shape of river delta is controlled by balance between watershed processes that supply sediment and receiving basin processes that redistribute, sequester, and export that sediment. All the size, geometry, and location of the receiving basin also plays an important role in delta evolution.
As river deltas form at the ocean at or below sea level, they are highly prone to storm surges which are expected to occur more frequently due to climate change-fueled sea-level rise and coastal flooding.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists.
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
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.
