Answer:
Polluting energy system are given below.
Explanation:
- Polluting Energy Systems like the Industrial systems that are stationary power systems along with the mobile pollutant system like vehicles and examples of heating systems like those of the air furnaces, hot water boilers, and electric heat pump.
- Example of Propulsion System is spacecraft and aircraft from a launch vehicle. Turbines are also characterized by having a propulsion system. Cooling Systems like the coolants in vehicles, computers and air conditioners and refrigerators, etc.
- All these follow the traditional energy system models as they stay locked from outside and derive the system by the energy created due to electric induction.
Answer:
Explained below
Explanation:
In physics, we know that waves usually change direction when are refracted or when they penetrate layers with different densities.
Therefore, when a seismic wave penetrates penetrates the boundary of the earth's interior, part of it will be sent back and part will be transmitted into the medium as refraction occurs. When we record the reflected and refracted ray, it enables the calculation of the position of major boundaries in the Earth's interior. This also helps in providing information about the solid & liquid character as well physical properties of the various layers in the medium.
Shaded Relief map is the type of map that uses relief shading to simulate the appearance of sunlight and shadows. Dark shadows on the map depict steep mountains while the absence of shadow depict a flat land.
Another type of Relief map is Raised Relief Map which is a three dimensional plastic or vinyl map that portrays the physical features of the region.
This is for a few reasons. Firstly, Africans don't view themselves as Africans (most of them don't). They view themselves as from x tribe or y country. Because of this, much hostility is shared between groups, and so cooperating to harvest these things wouldn't be the easiest. Secondly, the Scramble for Africa basically ruined most chances Africa had of becoming a power, because the European nations came in & exploited most of the continent. Hope this helps!
