Answer:
A. Rock is heated near the core at Point A, and therefore becomes less dense. It rises towards Point B. As it moves from Point B to Point C, it is cooled and becomes denser, so it sinks at Point D.
Explanation:
The process illustrated is a convection current, something seen places like the earth's mantle and atmosphere. The hotter matter gets, the more excited its molecules become and the more they become expanded and distant from each other. (Bear in mind that there is the same amount of matter but it takes up more space, i.e. less dense). This is because the molecules are excited by the thermal energy and bounce off each other, pushing them apart.
Cold, closer to the surface (or outer space in terms of air), in turn causes the matter to shrink back into itself, which leads to the increase in density that causes it to sink and repeats the process.
The deca and wast creep into the soil and water causing pollution
If there are too many people that are retires there will be no working class therefore there will be a large problem when it comes to italys working people and there will be too many jobs and not enough people
Answer:
Precipitation infiltrates into the subsurface via sinkholes and flows through subterranean passages to the Green River Valley.
Explanation:
Precipitation: The greatest factor controlling infiltration is the amount and characteristics (intensity, duration, etc.) of precipitation that falls as rain or snow. Precipitation that infiltrates into the ground often seeps into streambeds over an extended period of time.
As precipitation infiltrates into the subsurface soil, it generally forms an unsaturated zone and a saturated zone. In the unsaturated zone, the voids—that is, the spaces between grains of gravel, sand, silt, clay, and cracks within rocks—contain both air and water. Although a lot of water can be present in the unsaturated zone, this water cannot be pumped by wells because it is held too tightly by capillary forces.
The upper part of the unsaturated zone is the soil-water zone. The soil zone is crisscrossed by roots, openings left by decayed roots, and animal and worm burrows, which allow the precipitation to infiltrate into the soil zone.
Water in the soil is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere. Below the unsaturated zone is a saturated zone where water completely fills the voids between rock and soil particles.
It would be "Vernacular, Formal, Perceptual"
