The correct answer is letter B. increase deposition of sediments upstream. The negative effect of using too much water for the irrigation of crops is that it wash out sediments and these sediments are brought down the water streams.
Because water is water. humans need water to survive, so if the water in the bottle is considered to be clean ( without any added chemicals) it is then against our rights.
The circle has two forms of equation - General Form and Standard Form. The general form of the equation of the circle would be x^2 + y^2 + Dx + Ey + F = 0. The constants of this equation are D , E and F. The way to use general form is to complete the square and then proceed the equation in standard form. In that way we can identify the radius and center of the given circle.
Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
Answer:
Explanation:
New Zealand is located in one of the most tectonically active regions of the world, the pacific ring of fire.
Volcanic activities is produced from uprising magma through the earth. They usually occur around plate boundaries on the surface of the earth.
New Zealand sits around an area where the Pacific plate subducts under the Indo-Australian plate. As the subduction occurs, the rocks beneath undergoes partial melting leading to the formation of magma. The magma reaches the surface in landward regions away from the subduction margins and series of volcanic arcs can form. These series of volcanoes typifies the tectonic setting of New Zealand and it is responsible for the vast volcanic activity in the region.
