What is a cataract how did they contribute to the survival of the ancient Egyptian civilization

Geography

KengaRu [80]3 years ago

A cataract is an area of a river where the elevation of the streambed changes too quickly or has to many boulders meaning people couldn't use part of the river as transportation.

This was a good thing because the cataracts effectively served as barriers so they could control travel. This meant that the Pharos found it impossible to control the land south of the first cataract. This ending up becoming the southern border of Ancient Egypt.

Hope this helped ☺️

The three parts of Thomas Aquinas's Summa Theologica focus on Man, Christ, and
Artyom0805 [142]

Answer:

<u>God</u>

Explanation:

The Summa Theologica was a compilation of detailed information pertaining to the worship of God, written by Thomas Aquinas. This compilation was composed of three distinct parts namely; Man, Christ and God. The first two parts and 90 questions of the third part were mainly the work of Thomas Aquinas.

His death limited the completion of this work, which was then augmented by the supplementary part- the commentaries made by Thomas Aquinas on Peter Lombard's sentences. The compilation was made between 1265 to 1273.

Use the diagrams to explain what must be done to add fractions worth different denominators.
artcher [175]
To add fractions with different denominators you must convert the denominators into the lowest common factor. Aka the multiple they all go into. You then times the numerator by what you timsed the denominator by to make sure they both have the same denominator.
Example:

2/5+4/10

They both go into 10.

4/10+4/10= 8/10. 2 became 4 because 5x2=10.

I hope this helped!

You could also simplify 8/10 into 4/5z

If a 100-year flood has recently occurred along a river, it is now less likely to experience a similar event in the near term.
Temka [501]

The statement is correct.

When a flood is giving a time-bonding term, such as the 100-year flood, in this statement, it means that it has been noticed that the floods from the particular river occur on approximately that much of a time span.

If there has been a flood recently, than it most probably means that there isn't going to be a flooding caused by that river for the foreseeable future.

Now, there's always exceptions, as the climate patters are changing constantly, and there's always surprises, but in general, in lot of regions of the world, there has been noticed a certain consistency in some natural occurrences.
