The question asks to identify the lowest layer of the Earth's atmosphere. To answer this, one needs to recall the different layers of the atmosphere and their order from the Earth's surface upwards.
Correct Option: D) The Troposphere is the lowest layer of the Earth's atmosphere, extending from the surface up to an average height of about 13 km. It is where all weather events take place.
The question asks about the primary location of the ozone layer within Earth's atmosphere. To answer this, one needs to recall the structure of the atmosphere and the characteristics of its different layers.
Correct Option: D) Stratosphere — The ozone layer is primarily located in the stratosphere, which is the second major layer of Earth's atmosphere, situated above the troposphere.
