Describe why scientists use two different models to represent the layers of the Earth.

Answers

Answer:

Scientists use models to help them understand and explain ideas. Models explain objects or systems in a more simple way. Models often only show only a part of a system. The real situation is more complicated. Models help scientists to make predictions about complex systems. Some models are something that you can see or touch. Other types of models use an idea or numbers. Each type is useful in certain ways.

Explanation:

Physical Models

A physical model is a representation of something using objects. It can be three-dimensional, like a globe. It can also be a two-dimensional drawing or diagram. Models are usually smaller and simpler than the real object. They most likely leave out some parts, but contain the important parts. In a good model the parts are made or drawn to scale. Physical models allow us to see, feel and move their parts. This allows us to better understand the real system.

In one or two sentences, explain why and how the map of africa has changed over time.

Answers

Answer:

When the first World Book was published in 1917, there were only two independent countries in Africa: Abyssinia (now Ethiopia) and Liberia. Together, they made up less than 5 percent of the land area of the continent. The rest of Africa was divided into colonies controlled by the European nations of Belgium, France, Germany, Italy, Portugal, Spain, and the United Kingdom.

Organized groups in some African colonies began demanding self-government early in the 1900’s. But a mass independence movement did not take shape until after World War II (1939-1945).

Some countries gained their independence relatively peacefully. In 1951, Libya, which was an Italian colony in 1917, became the first country in Africa to gain independence. In 1956, France granted Morocco and Tunisia independence. That same year, the United Kingdom granted Sudan independence as well. Other countries saw much bloodshed before their independence was granted. In Algeria, a bloody revolt raged against the French from 1954 until the country won independence in 1962. In Kenya, members of a movement called Mau Mau revolted against British control in the 1950’s. The revolt failed, but it contributed to Kenya’s eventual decolonization in 1963.

Explanation: Today, Africa is divided into 54 independent countries. Several European countries still control a few small islands: the Madeira Islands (controlled by Portugal), Mayotte and Réunion (France), and Saint Helena (United Kingdom).

Answers

When a cyclone's strongest winds do not exceed 61 kilometers (38 miles) per hour, it is called a tropical depression

Tropical cyclones are classified based on their wind speed. When the fastest sustained winds does not exceed 38 miles per hour (61 km per hour), it is called a tropical depression.

If the fastest wind is greater than 38 miles per hour (61 km per hour), it is called a tropical storm.

However, if the maximum sustained wind speed reaches 74 mile per hour (119 km per hour) it is referred to as a hurricane.

Answers

Answer: Rise high into the atmosphere and spread downwind of the smoke stack

Explanation:

When the air is unstable or the atmosphere is unstable this means there is a difference between high pressure and low pressure. The capacity to transport and disperse pollution will be more or higher.

The noxious gas like the Sulphur dioxide, nitrogen oxide, carbon oxide, and monoxide that results in urban smog will rise and spread more quickly. This will lead to the unblocking of sunlight. The gases originating from the boiler and other places where the combustion occurs will not adversely affect the environment.
