Many scientists feel that application of Geoengineering would not reduce the amount of greenhouse gases in the air.
Explanation:
Geoengineering or climate engineering includes a wide range of technological applications that are aimed to counter climate change and global warming.
These include solar geoengineering for blocking the sunlight before it warms the earth’s surface, ocean fertilization, artificial trees etc. The main drawback that scientists fear is the usage of various chemicals because of which these technologies would not reduce greenhouse gas.
Further imposing tax regulations or simply signing climate protocols would not reduce greenhouse gases. They are just for gaining emission incentives and people will easily evade regulations.
The main focus should be on cutting down anthropogenic emission of greenhouse gases. Hence all the industries, technologies, and the people must pledge work towards reducing the greenhouse gases

Answer:
Radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth because the oceanic crust is recycled too frequently at subduction zones,
Explanation:
Radiometric dating of basalt on the ocean floor can not provide us the absolute age of the planet earth due to the subduction. In the process of subduction oceanic plate went below the continental plate as it is less denser. It then melts there and its recycling takes place frequently. So the radiometric dating of basalt on oceanic plate can not provide us the true information regarding the age of the earth.

Answer:
d) Principle of Conservation of Matter
Explanation:
Principle of Conservation of Matter -
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .
