Scientific knowledge is knowledge that is 100% accurate and proven. other knowledge such as possibly prior knowledge is from ones own experience which may not be proven 100% correct. along with every other type of knowledge.
Answer:
Precipitation, Surface Runoff and Infiltration process
Explanation:
There different stages of the water cycle where the water comes back on earth due to the gravitational force are as follows-
Rainfall/Precipitation- The water vapour in the cloud undergoes the process of condensation, it leads to the occurrence of rainfall, where the water comes freely over the ground surface from a certain height.
Surface Runoff- These refer to the flow of water rapidly along a steep slope, under the influence of gravity that eventually adds to the streams, lakes and rivers.
Infiltration process- This is the process where the water from the earth's surface percolates through the rocks and flows downward and eventually mixes with the groundwater.
Answer:
Our atmosphere (air) is comprised of 78% of nitrogen. However, this nitrogen is in its elementary state (N₂) and therefore is quite inactive, so the plants can not use it directly. Changing the elementary nitrogen into more reactive forms (NH₃, NO₂, HNO₃) is occurring through the process called nitrogen fixation. It is happening via two processes.
First one is physical nitrogen fixation. When some type of atmospheric physical energy (lightning bolt, for example) reacts with N₂, it splits it in two very reactive N atoms, enabling them to react with oxygen in order to form NO₂.
Second process is biological nitrogen fixation. It's done by bacteria, special bacteria living in the soil, able to use elementary nitrogen for its metabolical pathways resulting in production of ammonia, which can be used by plants. It's noteworthy that bacteria are responsible for about 90% of all nitrogen fixation.
