Answer:
In a situation in which You land your inflatable boat on a sandbar at high tide in Southeast Alaska, which has a large semi-diurnal tide. You intend to be away from the boat for 12 hours but come back early after only 8 hours. Your boat is, unfortunately, 400m from shore.
You will have to wait B) 4 hours and 25 minutes
to be able to use your boat
Explanation:
The reason behind this is that the water movement makes objects floating in its surface move at a certain rhythm. Generally, this measure is variable but after having the data of 400 m movement in 8 hours. We just have to divide to find out the speed at which the water moves the objects on its surface. We divide 400 between the 8 hours to obtain. 50 meters of distance advance in a single hour. Therefore in 4 hours and 25 minutes, it will be at the correct distance to be reached out and used.
Carbon dioxide or CO2 is one of the main greenhouse gases that accelerates global warming.
A greenhouse is a place where a particularly cold or hot climate is maintained.
Scientifics use this analogy with gases like CO2 because what they generate is a coat that keeps the sun's rays inside the oxygen layer, so these rays enter and heat the earth, unable to escape.
Industrial factories and cars are the largest carbon emitters. It all started in the Industrial Revolution
The dispersion of pollutant gases in the atmosphere from their sources are modeled through plume. It incorporates a lot of factors like wind speed, wind direction, atmospheric temperature, height, type of terrain, overcast or clear skies and so much more. Basically, it can be summarized through unstable or stable conditions.
In unstable conditions, ground level deposition is more dispersed so the concentration is not too high. However, air pollution from elevated smokestacks are readily returned to the ground. In that case, it would still lead to concentrated ground air pollutant concentrations.
In stable conditions, elevated smokestacks are desirable because there is less atmospheric mixing. The concentration of the pollutants is more concentrated in the point sources. Hence, ground level concentration is low.
Answer:
the tigurs and ethrups rivers
Explanation:
The rivers were very important and gave people fertile soil and they became rich and traded.
Population change
Explanation:
The change in the number of people living in a city, county, state, province or nation is generally referred to as population change.
Population change is positive when there is an increase in population;
Population change is negative when there is a decrease in population.
- Population is dynamic and it changes over a length of time.
- Migration is one of the leading cause of population changes.
- When people move away from an area, it is called emigration. It is a negative population change
- When people moves to an area, it is positive population change called immigration.
- Other cause of population changes are war, vices, economy, employment opportunities, education etc.
