Earth's history and dating rocks
(3 pts) Name an element that can be used to date back billions of years?

(4 pts) What is the different between relative and absolute dating?

Answers

Answer 1
Potassium-argon dating
One of the most widely used is potassium–argon dating (K–Ar dating). Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.

absolute dating is based on calculations of the age of rock strata based on half lives of minerals, relative dating is based on the assumed age of fossils found in the strata and the laws of super imposition.

Answers

My friend told me about seeing massive rocks flying through the air; it sounded pretty dramatic to witness a major rock "fall" like that.

Also, while skiing in the mountains, we saw a huge "avalanche" where snow and ice mixed with rock fell and tumbled rapidly down the hillside into the adjacent valley.

The news reported a large amount of non-water saturated material moved downslope along a particular plane and deposited at the valley bottom, where it temporarily dammed a river. That's the third "Landslide" reported this week following some heavy rains.

The "Debris Flow" moved from the volcano's flank down into the valley and deposited rock and debris that buried infrastructure much like when a river floods its floodplains.

Hence, in this case, it is concluded that the current answers are Falls, Avalanche, Landslide, and Debris Flow.

2. Why we reduce a map?​

Answers

Answer:

Large scale maps are required for urban planning. These provide large space in which detailed information and even the smallest points can be shown. Therefore, at times map is quite big but we have to reduce it according to size of paper and need so that major features may be concentrated upon. Measure the length and width of the map. Divide the length and width by 2 if you are asked to reduce the map to half of its original size. For example, if the length and width of a map are 30cm and 20cm respectively, such a map should measure 15cm by 10cm if reduced to half its size.

In the process of compiling maps cartographers are often required to either reduce or enlarge maps. Reduction or enlargement involves change in the size. An enlargement provides the same map but proportionally larger than the original. A reduction gives the same map that is proportionally smaller than the original

WORTH 50 POINTS!!!!!!!!!!!I took from their sconces two flambeaux, and giving one to Fortunato bowed him through several suites of rooms to the archway that led into the vaults. I passed down a long and winding staircase, requesting him to be cautious as he followed. We came at length to the foot of the descent, and stood together on the damp ground of the catacombs of the Montresors.The gait of my friend was unsteady, and the bells upon his cap jingled as he strode."The pipe," said he."It is farther on," said I; "but observe the white webwork which gleams from these cavern walls." He turned towards me and looked into my eyes with two filmy orbs that distilled the rheum of intoxication."Nitre?" he asked, at length."Nitre," I replied. "How long have you had that cough!""Ugh! ugh! ugh! -- ugh! ugh! ugh! -- ugh! ugh! ugh! -- ugh! ugh! ugh! -- ugh! ugh! ugh! My poor friend found it impossible to reply for many minutes."It is nothing," he said, at last."Come," I said, with decision, we will go back; your health is precious. You are rich, respected, admired, beloved; you are happy as once I was. You are a man to be missed. For me it is no matter. We will go back; you will be ill and I cannot be responsible. Besides, there is Luchesi" --"Enough," he said; "the cough is a mere nothing; it will not kill me. I shall not die of a cough.""True -- true," I replied; "and, indeed, I had no intention of alarming you unnecessarily -- but you should use all proper caution. A draught of this Medoc will defend us from the damps."Here I knocked off the neck of a bottle which I drew from a long row of its fellows that lay upon the mould. "Drink," I said, presenting him the wine. He raised it to his lips with a leer. He paused and nodded to me familiarly, while his bells jingled."I drink," he said, "to the buried that repose around us.""And I to your long life."He again took my arm and we proceeded."These vaults," he said, are extensive.""The Montresors," I replied, "were a great numerous family.""I forget your arms.""A huge human foot d'or, in a field azure; the foot crushes a serpent rampant whose fangs are imbedded in the heel.""And the motto?""Nemo me impune lacessit.""Good!" he said.The wine sparkled in his eyes and the bells jingled. My own fancy grew warm with the Medoc. We had passed through walls of piled bones, with casks and puncheons intermingling, into the inmost recesses of the catacombs. I paused again, and this time I made bold to seize Fortunato by an arm above the elbow."The nitre!" I said: see it increases. It hangs like moss upon the vaults. We are below the river's bed. The drops of moisture trickle among the bones. Come, we will go back ere it is too late. Your cough" --"It is nothing" he said; "let us go on. But first, another draught of the Medoc."I broke and reached him a flagon of De Grave. He emptied it at a breath. His eyes flashed with a fierce light.
