Which graph shows logistic growth of a population? *

Ocean acidification impacts are: 1. 2. 3. 4.

____ [38]

Explanation:

In the 200-plus years since the industrial revolution began,concentration of carbon dioxide in the atmosphere has increased due to human actions.During this time,the pH of surface ocean waters has fallen by 0.1 pH units.This might not sound like much,but the pH scale is logarithmic,so this change represents approximately a 30 percent increase in acidility.

Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming t

vekshin1

Answer:

The correct answer is - Rotate the types of crops grown.

Explanation:

Crop rotation is the practice of growing the different types of crops sequentially on the same field to improve nutrients in the soil for better soil health and helps in fighting pest and weed pressure.

Different crops required different nutrients and therefore, rotating crops helps to not exploiting the same nutrients again and again. Rotating crops also helps in removing weeds and pests as different weeds and different pests associate with different crops.

Explain the three mechanisms of heat transfer in Earth’s atmosphere.

MariettaO [177]

Explanation:

There are three ways heat is transferred into and through the atmosphere.

radiation. conduction. convection.

Radiation

Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.

Conduction

Welding iron is transferring heat by conduction

Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.

Convection

convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere
