Answer:
On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the oldest unit in the center, the underlying structure is a syncline.
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.

Climate change can worsen the intensity of tropical storms (such as hurricanes, typhoons and cyclones) in several ways, including by making record rainfall more likely and by causing sea levels to rise, which can raise the risk of storm surges.
Answer:
b. Seasons would be less pronounced
Explanation:
Seasons happen as a result of tilt in the earth's axis, by the changing angles that sunlight strikes the Earth, a decrease in tilt would mean less extreme seasons meanin less tilt would mean less of a change in angle around the orbit and therefore cooler summers and warmer winters.
