4 Where are the major mineral potential sites of Ethiopia?
Answer:
Only few primary ore deposits are currently mined for Au and Ta in the Southern Ethiopian metamorphic terrain at Lega Dembi and Kenticha, respectively, or they are at an advanced stage of investigation, such as the Au and Fe deposits in the Western Ethiopian Shield (WES) at Tulu Kapi and Bikilal, respectively, and the Au deposit at Meli in the Northern Ethiopian metamorphic terrain.
Explanation:
The northern greenstone belt and the western greenstone are the major mineral potential sites of Ethiopia.
What is a Mineral?These are solids which exists in nature as pure substances and possesses a well defined crystal structure.

What is this answer AC=?
Answer:
6.7km
Explanation:
if you look at this triangle AC is the adjacent of angle A,so you have to use the tan ratio
tan50=opposite/adjacent
tan50=8/AC
tan50ac/tan50=8/tan50

Answer:
1) a) [tex]r_{R,I} = 1150\,m[/tex], b) [tex]r_{R,II} = 3400\,m[/tex], c) [tex]r_{R,III} = 2750\,m[/tex].
2) a) [tex]r_{R,I} = 45,2\,km[/tex], b) [tex]r_{R, II} = 28,15\,km[/tex], c) [tex]r_{R,III} = 51,8\,km[/tex].
Explanation:
The scale factor is defined by the following expression:
[tex]n = \frac{r_{S}}{r_{R}}[/tex] (1)
Where:
[tex]n[/tex] - Scale factor.
[tex]r_{S}[/tex] - Scale distance, in centimetres.
[tex]r_{R}[/tex] - Real distance, in centimetres.
1) If we know that [tex]n = \frac{1}{50000}[/tex], [tex]r_{S,I} = 2,3\,cm[/tex], [tex]r_{S,II} = 6,8\,cm[/tex] and [tex]r_{S,III} = 5,5\,cm[/tex], then the actual distances in metres are:
[tex]r_{R,I} = \frac{r_{S,I}}{n}[/tex]
[tex]r_{R,I} = \frac{2,3\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,I} = 115000\,cm[/tex]
[tex]r_{R,I} = 1150\,m[/tex]
[tex]r_{R,II} = \frac{r_{S,II}}{n}[/tex]
[tex]r_{R,II} = \frac{6,8\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,II} = 340000\,cm[/tex]
[tex]r_{R,II} = 3400\,m[/tex]
[tex]r_{R, III} = \frac{r_{S, III}}{n}[/tex]
[tex]r_{R,III} = \frac{5,5\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,III} = 275000\,cm[/tex]
[tex]r_{R,III} = 2750\,m[/tex]
2) If we know that [tex]n = \frac{1}{50000}[/tex], [tex]r_{S, I} = 90,4\,cm[/tex], [tex]r_{S, II} = 56,3\,cm[/tex] and [tex]r_{S,III} = 103,6\,cm[/tex], then the actual distance in kilometres is:
[tex]r_{R,I} = \frac{r_{S,I}}{n}[/tex]
[tex]r_{R,I} = \frac{90,4\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,I} = 4520000\,cm[/tex]
[tex]r_{R,I} = 45,2\,km[/tex]
[tex]r_{R,II} = \frac{r_{S,II}}{n}[/tex]
[tex]r_{R,II} = \frac{56,3\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,II} = 2815000\,cm[/tex]
[tex]r_{R, II} = 28,15\,km[/tex]
[tex]r_{R, III} = \frac{r_{S, III}}{n}[/tex]
[tex]r_{R,III} = \frac{103,6\,cm}{\frac{1}{50000} }[/tex]
[tex]r_{R,III} = 5180000\,cm[/tex]
[tex]r_{R,III} = 51,8\,km[/tex]
The challenge problems of temporary mobile settelements in ethiopia
Answer:
Most energy for domestic use in rural areas is derived primarily from firewood and charcoal; this has strained the remaining wood resources in the country. Ethiopia’s long dependence on these sources has contributed to the depletion of its trees and to the erosion of its soil. The government has begun to expand hydroelectric power generation with the intent to increase access to electricity in rural areas.

When a wave is too steep to support itself, the wavefront collapses creating a---- that advances up the shoreline
Answer:
When a wave is too steep to support itself, the wavefront collapses creating a break that advances up the shoreline
Explanation:
When waves are tall, with a great slope that makes them unstable, they break. Braking waves might occur inshore or offshore.
Offshore: Breaking waves in the deep sea occurs when the wind speed increases so fast that they exceed the speed of the waves. These last ones acquire additional energy from the winds increasing their slopes to the point of being so unstable that the water from the crest falls forward and breaks the wave. The most influencing factor in these breaking waves is the speed of the winds.Inshore: When waves are near the shore, the scarce water deepness increases the friction of the wave with the marine bottom, and consequently, the wave´s speed decreases progressively. The wave loses energy in the friction, the wave energy is concentrated in a lower length, and the wave grows in size. As it increases, it acquires a sharper slope. As deepness decreases, the wave base loses speed, but the crest does not. As the wave crest travels faster, the frontal face of the wave becomes concave. This change in shape continues until the wave can not support itself and it breaks. The break is not produced by the friction with the bottom, but by exceeding the slope limit values.Summarize the origins of beaches, spits, baymouth bars, tombolos, and barrier islands and discuss how each of these unique features form. a. the origins of beaches b. spits c. baymouth bars d. tombolos e. barrier islands

Describe the roles these organisms play in their ecosystem.
Answer & Explanation:
Producers are usually autotrophs such as green plants. Green plants produce organic matter and energy on their own in the presence of light with water and carbon dioxide through photosynthesis.
Primary consumers depend on the producers for their energy and food. Primary consumers eat producers and get their energy such as deer.
Decomposers are organisms that decompose or decaying organisms or break down organisms and during breaking down dead, they carry out the natural process of decomposition.

What property of Venus's continents is not shared with Earth's continents? They cover only a fraction of the entire surface. They rise above surrounding regions of the crust. They comprise large land masses. They were formed by tectonic activity. All of the items listed apply both to Earth and Venus.
Answer: All of the items listed apply both to Earth and Venus.
Explanation:
Venus has two continents which cover only a fraction of the entire planet just like the seven continents of Earth do on Earth. These continents rise up above the surrounding regions of the crust even though on Earth the surround regions are the oceans but on Venus it is land.
These continents comprise large land masses with Venus' two continents being the size of Australia and South America respectively. Just like on Earth, the continents on Venus were formed by tectonic activity resulting from tectonic plates crashing into one another.

19. The wettest climate region in Africa is 20. Rainfall in Mediterranean climate region is brought by the --winds
Answer:
Westerlies winds.
Explanation:
Westerlies winds is responsible which brought the rainfall in Mediterranean climate region. During the winter period, a reversal of winds occur due to which westerlies bring the moisture from the oceans to the land which cools, condenses and sinks to form clouds that leads to precipitation. That's why the winters are wet in the Mediterranean regions. Westerlies are the winds that comes from middle latitudes between 35 and 65 degrees latitude.

Answer:
Green chemistry.
Explanation:
Many flights between the Europe and north America are done by flying over the north pole and this is done to cut the time and save fuel costs.The airplanes saved fuel and time based on the principle of great circle route.
The principle of great circle route asserts the shortest distance between two places on the earth lies on the arc of a great circle.
Hence, most of airplane flies on the route principle to save cost and time.

Impact of line thunderstorms on farming in the interior of SA
Answer:
Hi. You did not say whether "SA" was referring to South Africa or South America, which prevents your question from being answered. However, we can consider that line thunderstorms have very negative impacts on agriculture in any region, as they present very violent storms that can destroy crops and damage the land.
Explanation:
Line thunderstorms are formed by instability lines of storm clouds, which create a constant storm lasting many hours, as the clouds continue to form in a constant manner and all have a large amount of water for precipitation.
This type of storm is accompanied by very strong winds and even small tornadoes. This can be very harmful to agriculture, as it floods the farmland and strong winds cause the crops to fall over, or be completely uprooted.
In other words, line thunderstorms can destroy crops and harm farmers.
