Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time. ... The physical, chemical and biological properties of the different soils can have a big effect on how to best manage them.
Answer: True
Explanation:
The index fossil are the fossils that are of animals and plants that remained preserved in the rock of the earth. It describes the particular span of the geological time or the environment. An index fossil can be easily recognized, is widely distributed and abundant.
The index fossil is the basis for defining the boundaries of the geological time scale with the correlation of the strata.
Those organisms which exhibited the short vertical range that is the life span on earth and the wide lateral range that is geographic distribution can be included as index fossil.
These fossils are indicative of the environment in which the organism used to live.
Attempting to persuade MPs, Mr Johnson said the deal allowed the UK to leave the EU bloc "whole and entire" and that it protected the Irish peace process.
"I hope very much now... that my fellow MPs in Westminster do now come together to get Brexit done, to get this excellent deal over the line and deliver Brexit without any more delay," he said.
MPs will debate and vote on whether to accept the deal on Saturday, during a special sitting in the House of Commons. Opposition leaders have indicated they will not throw their weight behind it without a second referendum on Brexit.
If the deal is rejected, attention will turn to whether Mr Johnson will ask the EU for a Brexit delay, as he is compelled to do under legislation. The Benn Act blocks Britain leaving the EU without a deal on 31 October but Mr Johnson seems intent on exiting on that date, deal or no deal.
On Thursday President of the European Commission Jean-Claude Juncker ruled out an extension, saying: "If we have a deal, we have a deal and there is not need for prolongation."
CH4 + 02 → H20 + CO2
balance equation
CH4 + 2O2 → 2H2O + CO2
4 ÷ ( 12 + 4 ) = 0.25 mol
1 : 2
no mole of H2O = 0.25 × 2 = 0.5 mol
mass of H2O = 0.5 × ( 2 + 16 ) = 9g
