Hi there! The answer is C. barbarian raids.
Local farmers were unable to feed the Roman population during the fall of the Roman Empire because of barbarian raids. Between the 4th and 5th century, large groups of people entered the Roman Empire, which caused state failure inside the Empire. This period is called the Migration Period and preluded the Middle Ages.
Answer:
1. Interstellar cloud is an accumulation of dust and gas in between stars .
2 . The outer planets are composed of low density gas .
3 . Meteorites is the most important source for determining the age of our Solar System .
Explanation:
1 . Interstellar cloud
It is formed by the accumulation of plasma , gas and dust in the galaxy .
An interstellar clouds are more sense than the interstellar medium .
The cloud are classified according the size , density and temperature of the cloud . The interstellar cloud is formed by dust and gas particles from a red giant .
2 . The composition of the outer planets are from , the low density gases.
3 . Meteorites -
A meteorites originates from the outer space , and is a solid piece of debris . it can pass through the surface of a moon or planet , and due to high pressure and chemical interactions , can make the meteorite burn , and hence is seen as a shooting star or falling star.
Is there a photo? I can’t really answer without a photo or anything..?
It's crucial for an engineer who is just beginning to design multi-story buildings to go logically through each stage of the design process. Below are six steps that make up this sequence.
Basic guidelines to design a multi-story building
Each stage includes general guidelines to assist the designer in rapidly and effectively coming up with a workable solution for a specific set of limitations. In order for the end result to be both logical and attractive, the designer must also understand some general principles of excellent design.
The stages of a building project are presented.
Defining a project: What it is, why it is being proposed, where it is, etc.
Putting the facts together and creating the brief - Recognizing the location and context.
Designing a scheme involves considering and creating choices and a thorough design of the numerous parts and pieces.
Drawings and specifications for construction information

The actual paths of winds—and of ocean currents, which are pushed by wind—are partly a result of the Coriolis effect. ... The key to the Coriolis effectlies in the Earth's rotation. The Earth rotates faster at the Equator than itdoes at the poles. This is because the Earth is wider at theEquator.
