WILL GIVE BRAINLIEST A student explains the Nebular theory of formation of the solar system as follows. "The solar system was fo

rmed from a slowly rotating cloud called nebula containing extremely cold gases. When these gases were heated up, the nebula contracted and became a flattened disk. As the nebula became smaller, it rotated more rapidly and became flattened at the poles. Gravitational force caused rings of gases to be left behind when the nebula contracted. At the center of the nebula, the gases combined to form the sun and the planets formed in the outer flattened portion of the disk." What is the flaw in the student's explanation? (1 point) gravitational forces did not help the nebula to contract the nebula consisted of hot gases which contracted on being cooled the speed of rotation of the nebula decreased when it became smaller planets were formed in the central core of the nebula instead of outer portion of disk

• What regions of the world tend to have the highest and lowest precipitation rates (compare tropics versus sub-tropics)? How do
Stels [109]

Answer:

Regions with a higher amount of rainfall are those of equatorial regions and those of the low rainfall are polar areas.

Explanation:

  • The regions in the tropics and the subtropics receive a significant amount of rainfall while the place at the places receives only 10 inches f rainfall and regions are dry annually with rain occurring only in summer.
  • The tropical areas are those that surround the earth equator and are found 23 degrees north and south. As the sun is usually in direct contact and this region comprise of 40% of the surface area and 35% of the earth's landmass. And remains warm to hot and moist year-round.
  • These regions are characterized by wet season and thus have most of the cyclonic activity through the year and this impacts the global distribution of water as the movement of the warm and cold water stakes form these regions, along with the variation in salinity.

In this unit, you learned how humans evolved from their earliest days to the beginning of civilizations in settled communities.
algol [13]

Answer:

 Sub-Saharan Africa is a lot like the half empty, half full glass. Although the region has many problems, it holds much hope for the future. On one hand, political and economic problems plague the region.

   The region's cities attract a high number of immigrants, increasing diversity as well as the ethnic conflict in the region. Population growth is putting a tremendous strain on the environment. Because of population growth, there are water shortages, unemployment, lack of housing, and inadequate services. On the other hand, there are still large areas of land that can be farmed to feed the population and provide crops for export.

   Governments are stabilizing, but government systems lack capacity, and representative government is increasing. Some government systems in the region are unstable. Many governments are unable to provide adequate services. Ethnic diversity and conflict continue to plague the region. On the other hand, most government systems are moving toward democratic, multiparty systems in which leaders are elected.

   Economic development is increasing, yet, there are many factors that describe the political situation that Sub-Saharan Africa is facing such as international debt, and weak government systems that hinder economic development. There are positives though. Foreign investment will aid the region's economic development, and globalization will play a role in the region's economic future. Technological advances will also expand employment opportunities. There are several methods dealing with water issues that affect the economics of the region. Water is moved from an area where it is abundant to an area experiencing a shortage, and desalinization is being implemented.

Social services are also improving. Nevertheless, there are a number of regional issues that must be addressed. Health issues in the region include malaria, schistosomiasis, and AIDS. Progress is being made, particularly in urban areas where clinics offer basic care. The status of women also varies throughout the region.
