3. Trilobite fossils have been found in rock that is 521 million years old. They have also been
found in rocks that are more than 252 million years old. Trilobite fossils have not been found in
younger or older rocks. What does this tell you!
(Mark the one best answer.)
А
Trilobites became extinct 252 million years ago.
B
Trilobites became extinct 521 million years ago.
C Trilobites lived on Earth for 252 million years.
O D Trilobites lived on Earth more than 521 million years ago
The evidence provided by the fossils means that Trilobites became extinct 252 million years ago and lived on Earth more than 521 million years ago.
Basically, a fossil is a remains which gives geologist information about the organism which lived in the past because when those organism dies, they decay and remain on or in the earth surface
Since the trilobite fossils are found in rock that are 521 million years and 252 million years old, then, it means that:
Trilobites became extinct 252 million years ago therefore, no other remains keep existing on rocks earlier.Trilobites lived on Earth more than 521 million years agoTherefore, the Option A and D is correct.

what caused the change in the air and soil temperature between 20 and 50 years after the field was abandoned
Industrialization is a process that brought negative influences on the earth's natural environment. One of them is climate change.
Industrialization was a process in which the production processes of different products were improved allowing the manufacture of more units with the following characteristics:
Less time wasted.Lower spending of money.Higher performance.Industrialization influenced most of the countries of the world and caused the great displacement of people from rural areas to cities. This displacement was because the agricultural and manual products produced by artisans and peasants could not compete in the market with the products of large industries.
After several years, humans have shown the negative consequences of this industrialized growth. Well, many of the machines used in these factories work with the combustion of fossil fuels, and the gases produced by them are released into the atmosphere.
On the other hand, the overproduction of products and the effects of marketing has increased the demand for unnecessary products with a very short useful life that increased human waste that pollutes nature.
These environmental damages were intensified by the action of the greenhouse effect because this phenomenon naturally balanced the Earth's temperature, but with the increasing production of gases in factories and other industries, there is a greater concentration of these gases in the atmosphere, which has led to progressive heating of the air and soil.
