Answer:
The marshes are defined as the type of wetland where the water covers the ground surface for a long period of time. Here, the trees are absent and are mostly dominated by the grasses and other small herbivore plants. They are commonly formed in delta type of environment where the rivers adds water into the seas. It forms an isolated and distinct ecosystem.
The marshes in nature, behaves like a filtration process as the vegetation that are present in marshes takes up more amount of nutrients for their growth and expansion. But, if it does not use up these excess nutrients then it cause water pollution comprising of nitrogen and phosphorous.
They also plays an important role in the reduction of damages that are caused by a flood.
The marshes are sometimes seasonal and it occurs when the height of the river level is relatively high, and it floods the grassland areas.
The marshes are of three types-
(1) Tidal salt marshes
(2) Tidal freshwater marshes
(3) Inland freshwater marshes.
Answer:
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.
Answer and Explanation:
At the time when Galileo lived, people believed in the geocentric model of the solar system, which claimed that earth was the center of the universe, where all the celestial bodies revolved around it. By using the microscope and discovering Jupiter's natural satellites, Galileo put geocentric systems to the test. This is because he showed that the earth was not the only planet that had celestial bodies rotating around it, other planets had this capacity, like Jupiter. Today we know that Galileo is correct, but his ideas were not well received at the time.
In relation to astronomy, the science of Galileo's time was based on the Aristotelian model, which stated that the celestial bodies were smooth and had a perfect, polished surface with no irregularities. Galileo also put this concept to the test, when he was able to visualize the surface of the moon with his telescope. He saw that the moon did not have a smooth surface, but a rough one, full of irregularities, mountains and caves just like the earth. Today we know that this is true, but one more this idea was not well received by the fellow citizens of Galileo, which caused his life imprisonment for heresy.
We can see that Galileo did not receive a correct judgment from the society in which he lived and suffered for it, even though he was not doing any harm to anyone.
A a landform that is naturally lower than its surroundings
The statement, “An arid or
semi-arid climate occurs where precipitation is greater than potential evaporation”,
is false. A semi-arid climate occurs where the recipitation is below the
potential evaporation. Regions that experiences arid climate receives less than
10 inches of rainfall in an entire year.
