I think it is A.burning of fossil fuels
The answer is actually pretty simple
Answer= 7.35 cm
Basically physical and chemical weathering (do not confuse with erosion, which involves movement) contribute to the destruction of mineral forms. In this case it breaks down the rocks, minerals and soils, creating slopes and hills. It may be caused by (any form of) water, wind, gravity, waves or sunlight.
Many impacts can be brought by global warming, here I would introduce two impact each on the aspect on ecosystem and agriculture.
On ecosystem:
1. Shift in distribution of plants:
The changes in climate brought by global warming will alter the natural distribution limits for vegetation. For example, forests are moving north into the ;and that was once Arctic tundra, while the growing season increased in northern high latitudes.
2. Extinction or endangerment of species
Species may not be able to cope with climate change unlike human, hence intolerance of the increasing temperature may led to the extinction of spices. For example, coral reef cannot survive under temperature over 30 degree Celsius hence facing the danger of extinction.
On agriculture:
3.Farm production lowered
A warmer climate would lead to a loss of soil moisture hence increasing the erosion rate, and the dry soil will lower the land productivity as crops cannot grow on these barren land, especially water thirsty crops such as rice.
4.Farm production destroyed
Pests may become more active given the shorter and warmer winter, while floods may be present more often given the rapidly rising sea level and the instability of the climate.
Hope it helps!
Answer:
Ways for pollution free environment are :-
- Follow the 3 Rs ⇻ Reduce, Reuse & Recycle.
- <u>Reduce</u> the consumption of plastic products (use glass bottles, paper bags etc.)
- <u>Reuse</u> old & worn out things instead of throwing them away.
- <u>Recycle</u> your paper & plastic products.
- Use public transport, cycles or just walk ➟ this will reduce smoke & hence will reduce air pollution.
- Turn off the lights & fans when not in use ⎆ for less consumption of energy.
