1 answer:

7 0

The common component of air pollution is particulate matter (PM). This is a complex mixture of extremely small particles and liquid droplets.

The major components of PM are sulphates, nitrates, ammonia, sodium chloride, black carbon, dust particles and water. PM comes from dust , soot, smoke, industry and vehicle exhaust as well as complex chemical reactions with other pollutants.

Burning of fossil fuels produces sulphur dioxide . It is a colorless gas that pollutes the air and can cause health problems affecting the respiratory system.

What could a scientist do to determine what era the Eocene Period belongs to on the geologic time scale?

Burka [1]

Answer:

Option B) study information related to the Cenozoic era

Explanation:

The complete question is

Scientists discovered that the Eocene time period existed in Earths history around 34 MYA. What do they need to do to determine what time period Eocene belongs to on the geologic time scale?

A) learn what happened during Precambrian time

B) study information related to the Cenozoic era

C) view the timing of events in the Mesozoic era

D) research events that happened during the Paleozoic era

Solution -

The period of Eocene belong to the Cenozoic era. The Cenozoic era is divided into three periods-

a) The Paleogene – Existed between 65.5 to 23.03 million years ago

b) The Neogene - Existed between 23.03 to 2.6 million years ago

c) The Quaternary – Started some 2.6 million years ago and is continuing till present

The Paleogene is subdivided into three epochs –

A) The Paleocene – existed between 65.5 to 55.8 million years ago

B) The Eocene – existed between 55.8 to 33.9 million years ago and

C) The Oligocene – existed between 33.9 to 23.03 million years ago

Hence, studying about Cenozoic era will give information about the Eocene epoch

Hence, option B is correct
