<u>Answer:</u>
The units used to measure distances between parallels and between meridians are degrees, minutes, and seconds.
<u>Explanation:</u>
- The distance between two far-away latitudes or two far-away longitudes can be broadly measured in degrees.
- In order to pinpoint any two locations lying across two different latitudes or longitudes, the distance can be tracked down to minutes and seconds.
- The distance between two closest latitudes or two closest longitudes can only be measured in minutes and seconds because they would be placed only 59 minutes and 59 seconds apart.
Seismometers are tools which measure motion in the ground including seismic waves generated by earthquakes, volcanoes, and other activities which might create seismic waves. Seismometers measure any movement of seismic activity in the earth and today this is done by electronic means whereby the machine measures any changes in seismic activity in the surrounding areas of the seismometer. The first seismometer is believed to have been invented by Zhang Heng of China's Han Dynasty in 132 AD.
Answer:
c. are renewable
Explanation:
There are many energy sources that the humans have learned to use and exploit. Some resources are non-renewable, while some a re renewable. The non-renewable tend to be cheaper for the time being, and they also tend to produce more energy, but the problem is that the reserves will eventually run out. On the other side, the renewable resources are constantly out there, and they can not be spent, which gives them the advantage on the long run.
The alternative energy sources have been more and more in the focus, especially when it comes to the more developed nations. The main reasons for this are that the fossil fuels will eventually run out, and that they are more environment friendly. This has led to development of technology that is able to harvest energy from the sun, water, and wind, all which are natural resources that are constantly present and can not be spent. Some nations have invested so much in these resources that they have gradually started to replace the fossil fuels, with the end goal being stopping the usage of the fossil fuels totally.
Answer: Africa includes the rich source of water drainage in the form of rivers.

The course travelled by the major rivers in Africa are as follows:
1. Congo: Center to north and further to the Western region finally drains into the Atlantic Ocean.
2. Nile: Northeastern part to the North and then finally to the Mediterranean Sea.

The false statement is - B. This map projection does not distort shapes.
The map shown on the image is a Mollweide projection map. This is a map that has an elliptical shape, unlike most of the maps that have a rectangular shape. It is a map that pretty accurately manages to depict the Earth's continents with their right sizes.
Unfortunately, it can not be said that the map is without flaws. It is a map that has distortions, as all the others do, but it is still a map where the distortions are very small, thus the depiction is much accurate than on most of the other map projections.
