The correct answer is option A, that is, a landfill in the region of nonporous bedrock.
A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.
A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.
Answer: Van der Waals forces
Explanation:
Van der Waals forces are weak intermolecular forces that depend on the distance between two particles. They are caused by correlations in the change in polarization between two nearby particles. To put it in other words, when a particle changes its polarization (becomes more positive on one end and more negative on the other), so does the adjacent particle, and the next one, and so on. This causes these particles to stick together weakly.
The tiny "hairs" increase the surface area of the gecko's feet in contact with the wall, which makes the bond stronger and allows it to support all of its weight.
Because experiments have shown that geckos stick well to both hydrophobic and hydrophilic surfaces, we can assume there aren't any hydrogen bonds present.
Ionic bonds can't be present either because geckos wouldn't stick to electrically neutral surfaces, as these bonds require charged molecules.
The storage areas are called : Reservoirs Reservoirs can both be made by nature or crafted by men. In order to make our lives became easier , we could create our own reservioir by digging up an open land to form a space that could contain water when its raining, as a back up resources when the lake or rivers are drying up
On the earth surface
Explanation:
The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.
- The sun releases radiation in form of short-wave.
- They are usually more energetic and with short wavelength and a high frequency.
- When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
- Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
- When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
- Earth is cooler than the sun
- When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
- When the short waves are absorbed, they lose some of their their energy to the earth surface.
- The remainder is radiated back as less energetic long waves.
- The hotter a body is, the more energetic the radiation it releases.
