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 ☺️

Which of the following makes the cascade mountains a good place for mining? Select all that apply.
Alex777 [14]

<u>Answer</u>: e) Volcanic activity in the region leaves behind valuable minerals.

<u />

<u>Explanation</u>: Volcanic activity has played an important role in the creation of the Cascade Mountains as they were originally created through the subduction of two continental plates.

It is well known that gold deposists are often found through volcanic systems. Water heated by volcanoes will become very acid and thus dissolve surrounding rocks. This water that will contain gold and other metals will then follow fractures through the bedrock towards the surface. In time, these will turn into gold veins or lodes.

Masteriza [31]

Answer:

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava.

balu736 [363]

Answer:

biosphere

atmosphere

lithosphere

hydrosphere

Explanation:

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres.
