Why are models important ?

Answers

Answer 1

Explanation:

Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly

Answer 2

Answer:

Models allow the scientist to describe objects that are too large or too small to be seen normally, things that don't exist anymore, things that have not been created, and events that occur too slowly or too quickly to be seen. Models also communicate ideas that might be difficult to describe otherwise.

Explanation:

edg. 2020

Another way of saying it would be:

Models are important because it allows scientist to help people better understand a subject that they wouldn't be able to understand, due to that fact that other variables prevent the subject from easily being seen and observed. Models also allow you to explain things in a way that is easier and simpler to explain.

Answers

Answer:

We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.

Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Explanation:

Answer:

Deforestation on rainforests and other natural environments can have a devastating effect on the whole world. First, it leads to the loss of many animal and plant species, decreasing the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. Deforestation also has a negative effect on climate change, as trees are able to absorbe an enormous amount of greenhouse gas emissions. Without them,  the greenhouse effect is amplified, worsening climate change.
