The geographic use of technology to view and record observations from a distance is known as remote sensing.
It replaces slower, steeply-priced statistics series at the ground, presenting rapid and repetitive coverage of extraordinarily huge areas for everyday programs, ranging from weather forecasts to reviews on herbal failures or climate change.
Remote sensing is the manner of detecting and tracking the physical characteristics of a place by using measuring its meditated and emitted radiation at a distance (commonly from a satellite or plane). special cameras gather remotely sensed photographs, which help researchers "experience" matters approximately the Earth.
Examples of passive far-flung sensors consist of film pictures, infrared, charge-coupled gadgets, and radiometers. active series, on the other hand, emits energy in order to experiment with objects and areas whereupon a sensor then detects and measures the radiation that is meditated or backscattered from the goal.

<u>Answer:
</u>
The build-up of three oxygen created our ozone layer around two billion years ago.
<u>Explanation:
</u>
- The ozone layer is a part of the stratosphere which is located right after the troposphere in the atmosphere of the Earth.
- The ozone gas is made up of the abundance of three oxygen molecules combining with the ultraviolet radiation emitted by the Sun.
- The development of the ozone layer happened around two billion years ago when the oxygen concentration levels on the planet began to rise slowly and gradually.

The second largest city in Brazil is Rio de Janeiro, while the third biggest is the capital Brasilia. Rio de Janeiro has an estimated population of around 6,5 million people while Brasilia has little less than 3 million. This makes Rio de Janeiro more than twice bigger in population than the capital of Brazil, Brasilia. But there's something interesting in here in the background, in the past 6 years the population of the second Rio de Janeiro has only increased by little over 9%, while Brasilia's population has increased by around 20% which is more than twice in increase, so if that trend continues in the coming few decades Brasilia will come on top of Rio de Janeiro very quickly.
