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: Option (C)
Explanation: Non renewable resources refers to those resources that cannot be regenerated after being used. This are also known as the conventional energy resources. They are formed from the decay of ancient planta and animals that were buried millions of years ago. For example, coal, petroleum, oil and natural gas.
This <u>amount of this resources are present on the earth in a very fixed amount and have great economic significance</u>. Since it is present in a very small amount, so it must be use carefully and if possible should make minimum use of it.
In order to sustain this resources, alternate renewable resources are being used.
Thus, the correct answer is option (C).
