A possible cause was a meteorite hit the earth. it caused many organisms to become extinct because it blocked out the Sun so plants couldn't grow and herbivores couldn't eat the plants and carnivores couldn't eat herbivores.
Answer: An erosion of soil which enters waterways
Explanation:
Acidic water is more poisonous to human, animal and plant life so if acidic water were to wash into a river that humans drink, the health risks posed to those humans would increase.
If there were plants and animals connected to the river, the risks to them would increase as well and disrupt their life cycle.
Acidic water does not make water more or less capable of soil erosion so the water being acidic would not contribute to soil erosion.
Answer:
Option (E)
Explanation:
Keeling has collected various data over the last few decades regarding the earth's atmospheric CO₂, and with the help of the photosynthesis process, he tried to determine the Keeling curve in the graph. He also considers that the earth climatic condition is the same everywhere like in the equator.
In the tropical and equatorial areas, the temperature is relatively high and also the area receives a maximum amount of sunlight and rainfall. This region supports a large number of species. This region has a higher concentration of CO₂. In addition to the increasing industrial development and consumption of fossil fuels, the CO₂ content has drastically increased over the last few decades.
From the experiment, he observed that the CO₂ content is maximum during the spring season as the plant matters undergo decomposition it releases a large amount of CO₂ into the atmosphere. But this CO₂ content is minimum during the autumn season because plants absorb the lesser amount of CO₂ in order to carry out the process of photosynthesis.
Thus, the Keeling curve shows a straight line sloping upward in the graph, which describes that the CO₂ content will be high in the tropical and near-equatorial environment.
Hence, the correct answer is option (E).
Answer:
Near water, change in elevation, or change in latitude.
A location at a high altitude will experience the cool summers and mild winters compared to a location at a low altitude.
Explanation:
Near water bodies, change in elevation, or change in latitude are geographic position that can be considered a control of temperature. If a location is present at a high altitude, it will experience cool summers and mild winters compared to a location at a low altitude because of lower pressure at the top. Lower pressure at higher altitudes is the main cause of colder temperature on top of a mountain than at sea level..
