which of the following is the best answer to the question, "why does the sun shine?"

In the forest, little sunlight is able to penetrate to the ground through the thick crown cover. as a result, little plant growth is found on the forest floor.

One of the most recognisable aspects of a forest ecosystem is the forest floor, also known as trash, duff, and the O horizon. It mostly comprises of vegetative elements that have been shed, such as leaves, branches, bark, and stems, which are present above the soil surface in varying states of decomposition. The forest floor is primarily made up of non-living organic detritus, although it also contains a broad range of animals and plants. Due to the abundance of decomposers and predators, usually in the form of invertebrates, fungi, algae, bacteria, and archaea, it is one of the most biologically diverse parts of the ecosystem. In tropical woods, where rates of metabolism and species variety are significantly higher than in colder regions, certain plants might be more readily visible.

Early Christian philosophy, especially in the patristic era, had a tendency to be intuitive and mystical and relies less on reasoning and argumentation. Additionally, it places less emphasis on Aristotle's methodical reasoning and more emphasis on the at times mystical beliefs of Plato.

Aristotle's theory that society develops out of human nature rather than from human vice and corruption was one that Aquinas endorsed. According to him, the state is a naturally occurring institution that comes from the nature of man. Man is a social and political animal by nature, with a predetermined and set aim.

Aristotle uses reasoning and observation in his natural philosophy to draw broad, causal conclusions. Aristotle, for instance, uses the idea of species to support his factual claims about the purposes and behaviors of particular creatures in his biology.

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.

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

Scientists 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.

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.

Explanation:

According to a 2014 report conducted by yale university and George Mason university, the majority of the public surveyed in the united states agreed that global warming is occurring, and 50% believed it was caused primarily by human activities.

Using fossil fuels like coal and oil has increased the quantity of carbon dioxide in the atmosphere during the last century (CO2). This increase is the consequence of burning coal or oil, which creates CO2 when oxygen and carbon dioxide in the air combine. A rise in greenhouse gas concentrations has been mostly attributed to the clearance of land for industrial, agricultural, and other human endeavors which in turn contributes to Global warming.

Answer:a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month, and feature hot temperatures all year-round. 

Explanation:

Whenever the sun, moonlight, and earth are lined up, the tidal ranges are at their greatest.

The term "tidal range" refers to the height difference between high tide and low tide. The rising and lowering of the tide is frequently accompanied by a horizontal water movement. The values after Morgat correction are: 1.50 - 0.10 Equals 1.40 m of low water. 7.10 - 0.40 ≈ 6.70 m is the high tide.

The seashore is more affected by this phenomenon as the tide range increases. However, the slope of the a beach or even other coastal landform is equally significant since, even in a macro-tidal setting, a steep cliff only offers a minimal difference in the region over which the waves and currents can operate.

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
