Which of the following is an advantage of vertical farming?

higher pest-control
less water waste
higher crop yields
less soil use

An advantage of vertical farming is , less soil  use.

Explanation:

Growing crops on vertical layers, stacked one after another is called vertical farming.In this method plants are grown in very small area without soil (Hydroponics) or along with fishes and other aquatic animals (aquaponics) or without any medium (Aeroponics).This system allows a controlled growth of plant in limited area .Involves very less use of soil in hydroponics it also uses less water in case of aeroponics.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
