The formation of the earth and other planetary bodies through the process of condensation and planetary accretion was essentially complete about how many years ago

Answers

Answer:

Primitive meteorites preserve the chemical and isotopic composition of the first aggregates that formed from dust and gas in the solar nebula during the earliest stages of solar system evolution. Gradual increase in the size of solid bodies from dust to aggregates and then to planetesimals finally led to the formation of planets within a few to tens of million years after the start of condensation. Thus the rocky planets of the inner solar system are likely the result of the accumulation of numerous smaller primitive as well as differentiated bodies. The chemically most primitive known meteorites are chondrites and they consist mostly of metal and silicates.Explanation:

- Which region is globally significant because of its strategic location, its major oil reserve
and its historic importance as the birthplace of three major religions?

Answers

Answer:

The region in question is the Middle East (Southwest Asia).

Explanation:

The Middle East is a region of great importance, both historically and in the present. The importance of this region can be seen in its strategic location, oil, and gas reserves, as well as being the birthplace of three major religions. Unfortunately, all of these things have also been the reason for continuous conflict.

Answers

Explanation:

illustrating percentages.

showing how parts make up a whole.

showing how trends change over time.

comparing information from different sources.

A line graph like this one is most helpful for showing how trends change over time. The correct option is c.

Line graphs are used to chart changes over short and long time periods. Line graphs are preferable to bar graphs when there are little changes. Line graphs can also be used to compare changes in more than one group during the same time period.

A line graph is a type of graph that is widely used to show change over time as a set of data points linked by segments of straight lines on two axes. As a result, the line graph aids in determining the relationship among two sets of values, with one set of information always being dependant on the other.

What is the HELIOCENTRIC model of the solar system?

Answers

Answer:

The heliocentric model of the solar system is the one that suggests that the sun is in the center of the universe and everything revolves around it.

Explanation:

There have been few models throughout history when it comes to the arrangement and hierarchy of the objects in space. Most of them have been wrong, though they have persisted for a very long time. Some, like the heliocentric model, got some basics right, but it still had some mistakes which from today's perspective are big ones.

The heliocentric model suggests that the Sun is the center of the universe, with all other objects in space orbiting around it. Now, it did guess right that the planets in the solar system revolve around it and that it is in the center of it, but it made a big mistake by putting the Sun in the center of the universe, not just the solar system. Not just that the Sun is not in the center of the universe, it is not even close to the center of the galaxy in which it is, nor it is the largest object or the one with the biggest gravity so that it attracts everything around to revolve around it.
