Answer:
Even though globes are showing Earth more accurately, the maps are still used because they are more practical.
Explanation:
Earth is generally shown with two methods, one being the maps (map projections) and the other being globes. Both are used and will be used, as both have several advantages, but also several disadvantages. Despite globes being closer and more accurate in their representation of Earth, the maps are still used because they are much more practical.
The globes show Earth very close to its true form, though they are made as a ball, not as an ellipsoid. Anyhow, the globes don't have distortions of areas, so the sizes and locations are accurate on them. On the other hand, globes are highly impractical because of their shape, as they are don't often fit in standard backpacks or bags, and can easily be broken or damaged. Also, we can not see the entire Earth at any moment, so it is hard to make comparisons by using them.
The maps, on the other side, do have inaccuracies, mostly by having distortions, be it around the Equator or around the poles. Despite this, they have a relatively good accuracy that in most cases is enough for practical usage. Also, their form and weight make them easy to use, move from place to place, and the entire world can be seen at the same time, thus they are very practical when it comes to making comparisons.
Answer:
Correlation
Explanation:
Correlation simply means matching rocks or strata's of the same age. This rock units or sedimentary strata's may be matched from same region or even different continents.
In correlation the major task is to establish time equivalency of various rocks or sedimentary strata's.
In correlation of rock unit or sedimentary strata, Geologist looks at the physical continuity. For example a sedimentary strata from a region having a particular sequence of rock or sedimentary strata . That same pattern of sequence may be found in another region . With the similarity in the sequence stratigraphy ( sediment layering), Geologist can infer the similarity in age of both strata's.
Fossil contents present in different strata; if similar fossil contents found in different regions, geologist can determine the age similarities.
The first picture indicates strata correlation using fossil similarities while the second picture uses the physical continuity like lithology to correlates strata's
The best answer is reduction in acid rain.
Acid rain is rainfall which has been rendered acidic by pollutants in the atmosphere. This kind of rain is typically harmful to forests and lakes.
The main cause of acid rain is human activities. The burning of fossil fuels such coal in electrical generating plants and crude oil products such as gasoline and diesel in car engine releases sulphur dioxide and nitrogen oxide into the atmosphere.
These compounds mix with water very high up in the atmosphere and form acid pollutants which fall on the ground as acid rain.
Use of clean energy will eliminate burning of fossil fuels and thus no acid rain will be produced.
