Explanation:
Carbon dioxide and methane are called greenhouse gases. The property of greenhouse gases is they they heat energy in them and does not let it escape.
Both Carbon dioxide and methane when present in atmosphere, absorb heat from sun and heat which would is reflected from the Earth's surface. With increase in fuel consumption release of these gases has grown tremandously. Thus, with increase in Carbon dioxide and methane more and more heat is being trapped in the atmosphere and therefore, the Earth's average is rising decade after decade.
Answer:
Unconformities are a surface of contact between two groups of unconformable strata.
There are three kinds of unconformities: disconformities, nonconformities, and angular unconformities.
The cos 60° would also equal 1/2
Answer:
A hydrometer is a instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces it's own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water
