Answer: 1. recollapsing universe
4. critical universe
3. coasting universe
2. accelerating universe
Explanation:
The universe is continually growing and galaxies are moving apart relative to one another.
These four models foresee the expansion and possible contraction of the universe.
Recollapsing universe: this model predicts that galaxies will stop growing apart and start getting closer to one another. It predicts that there is enough density to stop the growth of the universe in the future.
Critical universe: the universe has the same density as the critical density. This is the difference between the density the universe requires to stop and that of a universe with too little density to ever stop expanding
.
Coasting universe: has enough density to enable galaxies to keep growing apart
, in essence, less than the critical density.
Accelerating universe: this model explains that the distance of far-off galaxies is growing exponentially from an observer over time.
Soil texture is defined as the relative ratios of particle diameter that comprise the soil.
Texture refers to the particle size. The average size of a soil particle is determined by the relative proportions of sand, silt, and clay in the soil. The average size of soil particles geography increases as the quantity of sand in the soil increases, and the resulting soil gets coarser in texture. Conversely, increasing the quantity of clay in the soil reduces the average diameter of the soil particles, resulting in a finer-textured soil. Locate the percentages of clay and silt on the triangular textural diagram's silt and clay side lines, respectively. Then, in the first scenario, draw lines thru these points inwards, perpendicular to the clay side.

In many developing countries urban areas are magnets that attract people from small towns and the rural areas, because cities offer more hope of jobs, education, health care, and better living standards. Big cities in particular are economic, social, and cultural centers.
