Imagine being caught in a powerful storm with spiraling winds surging at speeds ranging from 74 to 160 mph. This intense weather system that typically forms in the tropical region of the earth is called a hurricane. It can cause a lot of destruction both in the water and on land.

Freshwater
The freshwater biome is a fascinating ecosystem, containing a plethora of lifeforms in various locations on every continent. To be considered “freshwater,” the water must have a low concentration of salt, generally less than 1 percent. This includes lakes, rivers, streams, wetlands, and other bodies of water. The plants and animals that inhabit the freshwater biome are adapted to...
hydropower
Hydroelectric power, or hydropower, refers to using moving water to generate electricity. Water flowing downhill turns turbines that drive electric generators. Reservoirs created by dams allow operators to precisely control the rate of water flow and the amount of power produced. A release pipe called a penstock concentrates the force of the elevated water in the reservoir. As long...
Geothermal power station
Fossil fuels have been the primary source of energy for human civilization since the start of the industrial revolution. While coal, oil and natural gas still supply most of the world’s energy, growing concerns about dwindling supplies and the carbon released when these fuels are burned have spurred a search for clean, renewable energy sources. While wind and solar...
Garbage On Rocks
Water is, perhaps, the most precious resource available on the planet. For a large amount of life to exist on Earth, access to fresh water is crucial. Despite the fact that water comprises more than 70 percent of the planet’s surface, only about 2.5 percent of this water can be qualified as “fresh.” Though ample water can be found...
Forest Being Cleared
Imagine a world without rain forests: no centuries-old trees to see and no unique animals to watch. That world could become reality in a hundred years if deforestation continues at the rate it’s happening today. Right now, forests cover about 30 percent of the Earth’s landmass. However, that number is quickly dropping as millions of acres of forests are...
What Is Soil Conservation and What Do I Need To Know About It? There is a lot of journalistic coverage about conserving forests, oceans, and energy, which are all extremely important for the environment. Soil does not currently receive as much attention, however, without adequately fertile soil, agriculture would disappear and humanity along with it. Soil erosion damages surrounding water...
Urbanization is something that eventually happens in any developing country, as the population condenses into smaller cities and towns. Agriculture begins to decline, and industrialization fuels the move from rural areas to urban ones.There are some positives and negatives to urbanization. When done correctly, urbanization means a greater variety of opportunity for residents. If it gets out of hand,...
While most people have a general understanding of what pollution is and how it is caused, most people have not heard about thermal pollution. The basic idea of pollution that most people know about includes air pollution from carbon emissions in vehicles and general pollution through littering and use harmful chemicals. A lot of people have never heard of thermal...
