The earth is the 3rd planet from the sun. it receives just the right amount of heat from the sun, which contributes to the planet's life-supporting
atmosphere, water cycle, and climate
gravity, climate, and tectonic activity
atmosphere, climate, and gravity
water cycle, evaporation, and atmosphere

The correct answer is atmosphere, water cycle, and climate

The Sun is the main source of energy on the earth. The heat that reaches the earth is in adequate amount so that life could be possible on earth.

The atmosphere on the earth has optimum amount of mixture of gases, water vapor and other constituents that supports life.

Water is the most important component of all living beings on earth and hence water cycle is very important for the pressence of life on earth. Sun regulates the water cycle.

Climate on the earth is also regulated by the time of exposure of sunlight on the earth.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
