The soil that occurs in regions with extreme wet and dry seasons is known as "black soil."
Black soil:
- Chernozem is another name for black soil.
- It is largely composed of humus, phosphoric acid, phosphorus, and ammonia.
- Exceptionally small or clay-like particles constitute black soils.
- Deep gaps form during warmer weather, resulting in appropriate aeration.
Black soil characteristics include:
- It is extremely fertile and has a clay-like texture.
- At 25°C, the pH of black soil ranges from 7.2 to 8.5.
- The soil has high levels of potash, calcium, and magnesium but low levels of nitrate and phosphate.
- It is often soft when damp but hardens as it dries.

Transform: The plates slide past each other, one going forwards, the other going back, kind of grinding each other. A Transform Boundary is also a fault, so it causes Earthquakes mostly.
Convergent: When two plates collide with each other. They form subduction mostly and trenches. They can also create volcanoes or volcanic islands.
Divergent: When two boundaries move away from each other. They form rift valleys, mountain ranges
Answer:
Economic b/c people produce various goods and services
<span>first thing you need to do is find the area of the circle
A=(pi)r^2
You don't know r, but you do know the diameter is 10, and the diameter is twice the radius so r=5
Then plug that into the area formula, and you'll get A=25pi or 78.54 ft^2
If one bag covers 2 ft^2, then divide your area by 2 and round up to get the number of bags of concrete (40)
hope i helped !!!</span>
Answer:
For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone.
