Answer:
The total mass of water in on Earth's surface is 
.
Explanation:
Total planetary surface area = T = 
Total land area of planet = L = 
Total water area of planet = W
T = L + W
Volume = Area × Depth
Volume of water on earth = V
V= 
Total mass of total water on the earth = M
Density of the water,D = 1 g/mL = 0.001 kg/0.001 L=1 kg/L
1 g - 0.001 kg
1 mL = 0.001 L
The total mass of water in on Earth's surface is .
Answer:
Coal is made by heating of woody plant material, and oil is made by heating of algae.
Explanation:
The coal and the oil are both fossil fuels. They have both been very important for the development that the humans have experienced since the Industrial Revolution as they were what provided the energy needed for this process, and they still do.
The coal is a fossil fuel that has formed from woody material, mostly from the Carboniferous forests. Once these forests collapsed, they were quickly covered with water, mud, and sediments. Over time they were covered with even more sediments, so they were getting deeper into the crust. As they were getting deeper into the crust this material was exposed to higher temperatures and pressures, leading to the formation of the coal over the course of millions of years.
The oil is a fossil fuel that has formed from the remains of the marine life, mostly algae. As the algae and the other marine organisms have been dying out, they have fallen on the bottom of the oceans, quickly being covered with the soft sediments. As more and more sediments have been placed on top of them, they too were getting deeper into the crust, so they were also exposed to higher temperatures and pressures, eventually leading to the formation of the oil over the course of millions of years.
Yes, the earth one was just one huge ocean.
The 3 largest rivers in South Asia are:
1.The Yangtze River
The Yangtze River is the longest river in China and the third longest in the world, measuring an impressive 6,380 kilometres in length. Steeped in myth and legend, vertical limestone cliffs line the river as it rises up to the mountains of Tibet.
2. The Mekong River
The Mekong River is an important source of water in Southeast Asia, measuring 4,350 kilometres in length. The river flows from the Tibetan Plateau through China, Myanmar, Laos, Thailand, Cambodia, and finally, Vietnam.
3.Brahmaputra River
One of Asia’s major rivers, the Brahmaputra River flows through China, India and Bangladesh. The river originates in the Tibetan Himalayas and travels almost 2,900 kilometres in length.
