Answer: As altitude increases, atmospheric pressure decreases
Explanation:
Atmospheric pressure
is defined as the force
per unit area
the air that forms the atmosphere exerts on the Earth's surface:
![P=\frac{F}{S}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BF%7D%7BS%7D)
It should be noted that as the altitude increases less air is above and, therefore the air weights less. This is because the atmosphere losses density as we ascend, causing less air.
However, it is important to point out this decrease in pressure is not linear, since at the beginning (in the first kilometers above sea level) it reduces more rapidly than in the next kilometers above. That is why this relationship between atmospheric pressure and altitude is exponential.
How does the Earth create a magnetic field?
The Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth.
The major geological process of Ethiopia are:
- Weathering.
- Mass transfer.
- Erosion and deposition.
Note that they are said to act on the volcanic and structural landforms by changing , roughening and reducing them to the minimum. The landmass of Ethiopia, is known to be as a result of the both effect of endogenic and exogenic processes.
<h3>What are those event about?</h3>
The above Events are known to greatly alter or created the Ethiopian geology as it brought about the putting together and also the break-up of Gondwana and the now aday rifting that took place in Africa.
So, The major geological process of Ethiopia are:
- Weathering.
- Mass transfer.
- Erosion and deposition.

Answer: C) Three
Explanation: In 1770 captain James Cook landed and claimed the territory for the British crown. thereafter it was used as a prison for prisoners fron Great Britain. by 1851 gold was discovered in New South Wales and Victoria, which meant that many gold diggers landed in Australia attracted by the precious metal. During the 50´s, important projects were developed, such as the snowy Mountain Hydroelectric Project. There were several labor or coalition governments that carried out important reforms such as taxation, climate change policies and those related to health and education.
