How humans affect the biogeochemical cycles?
Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.
What are the 2 main ways humans have impacted the biogeochemical cycle of carbon?
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
Which statement best describes a human influence on the biogeochemical cycles?
Answer: A) Increased eutrophication caused by high levels of nitrogen and phosphorus. Explanation: The balanced recycling of ‘inorganic matter’ between organisms and their environment to sustain equilibrium is known as biogeochemical cycle.
What are the factors that can disrupt the biogeochemical cycles?
Ecosystems have been damaged by a variety of human activities that alter the natural biogeochemical cycles due to pollution, oil spills, and events causing global climate change.
What is one negative effect of human influence on cycles of matter?
Human activities have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
What is one negative effect of human influence on cycles of matter Brainly?
Due deforestation there are less number of tress which results in less amount of oxygen being released in the atmosphere hence more carbon dioxide in the environment contributes to the climate change. Carbon dioxide is the principal greenhouse gas that insulates the earth so more Carbon dioxide means a warmer earth.
What process plays an important role in the biogeochemical cycles?
So,in short the answer is decomposition.
Which human activity would most likely decrease the amount of carbon in the atmosphere?
Answer: it is burning wood.
Which statement best describes a negative consequence of humans use of excess water?
Which statement describes a negative consequence of humans’ use of excess water? It increases runoff, which carries fertilizers. What protects the earths surface? Which two processes allow water to enter the atmosphere?
Which best describes a possible negative impact of irrigation of farmland?
excess of irrigation may result in the pollution of the groundwater. Explanation: A large number of chemical insecticides and pesticides are spread to increase the growth of different types of crops.
Which disruption in the water cycle would most likely affect photosynthesis?
Heat causes an excess of transpiration describes a disruption in the water cycle that could affect photosynthesis.
How does this most likely affect photosynthesis?
As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. … If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis.
What would most likely happen if there were no condensation?
If there was no condensation stage in the water cycle, there would be no precipitation, and the water cycle would stop.
What would most likely happen if there was no condensation stage in the water cycle?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds. … From clouds come rain. With no clouds, there would be no rain.
How would Earth most likely be affected if less water evaporates from the oceans during the water cycle?
How would Earth most likely be affected if less water evaporated from the oceans during the water cycle? Ocean water levels would increase and there would be less precipitation.
What would most likely happen if it didn’t rain in a certain area for a long period of time?
How do droughts happen? Droughts happen when there is not enough rain for a long period of time. It’s not like a dry spell – there is so little precipitation (rain, snow, sleet or any kind of moisture) that a whole region starts to dry out.
What would happen if Sun was removed from the water cycle?
Water constantly moves around the Earth and changes between solid, liquid and gas. … Without the Sun there would be no water cycle, which means no clouds, no rain—no weather!” “And without the Sun’s heat, the world’s oceans would be frozen!” added Marisol.
How cold would Earth be without the sun?
Sun, the glowing planet in the sky. For us on earth, it is a source of life. Even in Antarctica, the coldest place on our planet, temperatures seldom drop below minus 50°C. Without the sun’s radiation, the temperature would be anywhere near the absolute zero of minus 273°C.
What if the sun exploded?
For Earth to be completely safe from a supernova, we’d need to be at least 50 to 100 light-years away! But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn’t be strong enough to destroy the whole Earth. Only the side facing the Sun would boil away instantly.
