Explanation:
The water cycle is important because water sustains all life on Earth. Through a series of evaporation, transpiration, condensation, precipitation, infiltration, runoff, and other smaller processes, the water cycle keeps the Earth's water clean, distributes the water across the planet's surface, maintains aquatic ecosystems, and aids in the process of plant growth. The water cycle not only keeps all living things alive, but it's become an important tool for the modern human race. Climate change is altering patterns of weather and water around the world.

Answer:
The machine-gun was one of the deadliest weapons of the Western Front, causing thousands of casualties. It was a relatively new weapon at the start of the war, but British and German forces soon realised its potential as a killing machine, especially when fired from a fixed defensive position.
The Vickers machine-gun (above) was famed for its reliability and could fire over 600 rounds per minute and had a range of 4,500 yards. With proper handling, it could sustain a rate of fire for hours. This was providing that a necessary supply of belted ammunition, spare barrels and cooling water was available. When there was no water to hand, soldiers would urinate in the water jacket to keep the gun cool!

Answer:
Russia has built the Trans-Siberian Railroad to overcome the Friction of Space.
Explanation:
Russia is the largest country in the world, and on top of it, its territory is stretched by longitude which creates a situation where from the easternmost to westernmost point the distance is incredibly big. As both the eastern and western coasts are strategically very important for Russia, it is crucial that they are connected with infrastructure that will enable relatively fast and cheap transportation and traveling.
The solution came in the form of the Trans-Siberian Railroad. This is the longest railroad in the world, starting from Saint Petersburg, diverging into two lines, one going to Tyumen but before that at Yekaterinburg turning to merge with the other line at Chelyabinsk, continuing to Chita where it diverges again with one line going through Khabarovsk to Vladivostok while the other moving slightly through Mongolia, Harbin in China, and ending in Vladivostok.
