Chapter 21, Problem 1AC

Evidence of former life is called a

a. ghost.

b. fossil.

c. history.

d. relic.

Expert Solution & Answer

To determine

From the following options, the evidence of former life is:

ghost.

fossil.

history.

relic.

Answer to Problem 1AC

Solution:

Option (b) is the correct answer.

Explanation of Solution

Introduction:

Fossils provide the evidence of the events that have occurred in the history of the earth and the evolution of life.

Explanation:

Reason for correct option:

The word fossil originally meant anything dug up from the earth but now days it’s meaning has been changed to that and it gives the evidence of ancient organism, embedded in a rock for a long time.

Hence, option (b) is correct.

Reason for incorrect option:

Option (a) is incorrect because the word ghost does not show any evidence of life.

Option (c) is incorrect because it is due to the fossil the evidence of the ancient organism’s history is known.

Option (d) is incorrect because relic is another word for artefacts which can be any age.

Hence, options (a), (c) and (d) are incorrect options.

Conclusion:

The evidence of former life is obtained from a fossil.

Radiocarbon dating technique is used to estimate the age of: A. rocks B. monuments C. soil D. fossils

1. What is relative dating? 2. What is the law of superposition? 3. What is the law of original horizontally?

1. How old is a rock if the mineral biotite from the rock has 85,000 40K atoms and 15.000 40Ar atoms? Note: 40K decays to 40Ar with half-life = 1.3 billion years. 2. Isotopic analysis of a granitic intrusion indicates that 6.25 % of the original 40K is present. Analysis of a nearby basaltic intrusion indicates that 25 % of the original amount of 40K is present. What is the absolute age of both the granitic intrusion and the dike? What is the relationship between them? I. 3. Pebbles of an igneous rock are incorporated within a conglomerate. The pebbles yield a radiometric age of 200 million years. What can you say about age of the conglomerate based on this data? 4. A radioactive parent isotope with 600 atoms. After the decay, 450 daughter atoms were produced. Calculate the age of the rock if you know that the half-life of the parent isotope is 20 million years.
