If earth's total mass is 6 x 1024 kg, calculate the proportion of this lost every year. Show your working and express the answer as a number or percentage.
The proportion of total mass of Earth lost every year is 6 x 10²⁰ kg.
Principle of Uncertainty: -
Uncertainty in the definition of geographic objects is widely discussed among geographers, but is rarely formalized and integrated in geographic analysis. Major issues in geographical analysis are related to uncertainty in ambiguous, heterogeneous or differently applicable definitions of objects and concepts: city, region, continent, frontier, system, etc. Some of these objects can have non-ambiguous and crisp definitions through social conventions (as the limits of most administrative units, when they are not disputed), but many more suffer fundamental uncertainties in their theoretical, as well as practical, definitions. Coombes et al. (1979), for example, highlight the difficulties and the ambiguities inherent in a theoretical and practical definition of urban regions, even when ‘‘objective’’ data like commuter flows are used to identify functional regions.
The more accurate we measure position of the object, the more uncertain the momentum of the object becomes.
The uncertainty in the measurement of the mass of the Earth can be assumed to be (1 x 10⁻² %).
The proportion of the mass mass of Earth lost every year is calculated as follows;
m = (0.01/100) x 6 x 10²⁴ kg
m = 6 x 10²⁰ kg
Thus, the proportion of total mass of Earth lost every year is 6 x 10²⁰ kg.

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.

to get your bearings on the horizontal time axis of this plot, it is useful to calculate the age of the universe in seconds today. if you multiply the age of the universe in years by the number of seconds in a year, approximately what is the current age of the universe in seconds? a 4×10^17s
b 3×10^15s
c 1.4×10^10s
d 4×10^24s
If you get your bearings on the horizontal time axis of this plot, it's helpful to compute the age of the universe in seconds as of right now, which comes out to 4.36x10^17 seconds.
I believe that Planck's measurement of the universe's age, or roughly universe 13.82 billion years, is the accepted value. With the help of this horizontal time axis figure and the number of seconds in a non-leap year that can be calculated:
60 seconds in a minute
1 hour equals 3,600 seconds in 60 minutes.
Day is equal to 24 hours and 86,400 seconds.
1 year is equal to 31,536,000 days.
We can now take this value and multiply it by the universe's age in years: horizontal time axis
31.536,000 x 13.820 billion = 4.36 x 10^17 seconds
As a result, 4.36x1017 seconds is a good estimate of the universe's age in universe seconds.

A variety of physical mechanisms are responsible for cycles at each scale. Any given period's climate is a result of all of these nested mechanisms and cycles coming into play at the same time.
A mechanism that might cause a sudden change in the global climate would want to keep the following features:

TRUE/FALSE. some ocean species migrate vertically through the water column, becoming more common with increasing depth.
It is true that some ocean species move vertical migrations through the water column, becoming more widespread as the depth of the water increases.
Diel vertical migrations of marine fish are a very frequent phenomenon that happen in a variety of species and life cycle stages. Their relatively constant diel durations support the idea of an underlying circadian water rhythmicity. Since the pattern of vertical migration can be altered by a vertical migrations variety of conditions, the process of vertical migration also often appears to be facultative. A potential system having several restrictions on diel vertical migrations as an example. It is true that some ocean species move vertically through the water column, becoming water more widespread as the depth of the water increases.

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.
