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:
As it builds up the impacts of hazardous event.
Explanation:
- As Mexico is the one of the most seismically active zones and it sits on the intersecting tectonic plates which are bordered by the cocos plate and the North American plate and is along with the cost of the Mexico that form a subduction zone and these force thus cause about 40 earthquakes in a day.
- <u>As the Mexico city is built in a dry lake bed with a soft soil that has sand and clay the earthquake event amplifies the destruction. And cause violent shaking of the ground with deeper and denser soils that increase the magnitude of the events. Thus the densely populated areas are more prone to the earthquakes as the changes of the land-use patterns change the effects of hazards.</u>
Answer:
C. include global warming, which is greatly enhanced by society's production of greenhouse gas
Explanation:
Human activities such as burning of fossil fuel, industrial waste has lead to the emission of greenhouses such as carbondioxide, carbon monoxide, methane, chlorofloro carbon accumulation of which in the atmosphere leads to global warming as a result of the depletion of the ozone layer and the direct impact of sun on the earth.
The depleted ozone layer has lead to the constant and high temperature
that is affecting the earth.
Green plant,trees are natural users of carbondioxide but deforestation of this trees has also reduce the use of carbondioxide making it abundant in the atmosphere.
B. canadian territories are under a constitutional monarchy
Canada
still exists such that the Queen of England is the head of state or
formal representative of canada. However they are protected by a
constitution and act as an independent nation with a head of government
(the prime minister) taking care of actual governmental affairs. The
queen does not have direct power in the same manner as the prime
minister hence the division head of state vs head of government.
