Answer:
Abiotic
Explanation:
Clouds are condensed water droplets, high in the air. Clouds are non-living things, hence clouds are abiotic.
Biosphere reprezents all the living forms
geosphere includes bisphere, hidrosphere and atmosphere
hydrosphere represents the the water on Earth
atmosphere is the gas on Earth, so the correct answer is D - ATMOSPHERE
<em><u>Wetlands occurring in areas with a large amount of trees are most likely marshes.
</u></em>
Further Explanation:
The Wetlands are the areas that are flooded by water throughout the year and have oxygen – freeprocesses.It differentiates by the vegetation it has that is mostly the aquatic plants, adapting to unique hybrid soil. Wetlands are responsible for the water purification, processing of nutrients, water storage and support life and stabilizing of shorelines. It is also an ecosystem that supports a great variety of flora and fauna.
The wetland that is characterized by herbaceous vegetationis called marshes that are generally woody plants. Thesevegetation are found on the edges of the wetland and form a transition between the terrestrial and aquatic ecosystem, comprising of grasses, reeds, rushes and shrubby woody plants. The most important component that segregates it from the other wetlands are the swamps, mires that are characterized by acidic peat.

a) <u>TWO important causes for the variation in the temperature and/or salinity of an estuary as follows:</u>
Salinity will vary hourly, because of the tides. Temperature will vary depending on the time of year. Solar radiation, different in winter than in summer, changes the temperature.
b) <u>TWO roles that coastal wetlands play Ecologically</u>
- they provide a habitat for various wildlife
- provide nutrient cycling, or soak up excess nutrients.
<u>TWO roles that wetlands play Economically</u>
- they provide a location for fishing and other sources of recreation
- reduce flooding and erosion.
c) <u>THREE ways in which humans have had a negative impact on or have degraded coastal wetlands as follows:</u>
- They have removed wetlands for agricultural purposes
- more use of groundwater, which reduces the balance of the ecosystem
- have water pollution, plants harvest, and birds hunt.
d) Overused groundwater can be reduced by charging user fees to those who use it, as well as increasing the number of wildlife refugees, which will restrict available land for groundwater use.
<u>Explanation:</u>
Estuary is a land form that formed in the lower course of a river where river enters into the sea. Here temperature and salinity varies with solar radiation as the intensity of sun rays different season wise. During the time of tides salinity level does fluctuate.
Wetland is a very important feature of environment. It is also known as the kidney of environment and it acts as a natural habitat for the animals and economically important zone for the fishing. It is also a recreation zone. With increasing population over burden on agricultural land enhances adversities on environment.
The sea level is tied to glacial growth as a result of the changes that occur.
The glacial growth brings about a decrease in sea level.
Glacial growth occurs when water is evaporated and forms ice which is the
sold state of water as a result of the low temperature in the environment.
The ice formed brings about a decrease in sea level.
However, when the ice melts it leads to an increase in the sea level as the
liquid water formed from the ice which flows into the water bodies thereby
bringing about an increase.
