B. Rice
C. Soybeans
D. Wheat****

Crops grow well on the north China plain because the Huang river
A. Forms a barrier to animals that eat crops
B. Changes weather patterns in the area
C. Deposits fertile soil after floods
D. Carries pollution away from the fields

D is correct for the first one.

What is your answer for the second?

No.

C is right.

thank you

You're welcome.

soybeans is right on the first one

Hhghh

what is the second question?

for the first one i got b

To determine the staple crop of the north China plain, we need to analyze the options provided and consider the geographical characteristics of the region.

The options are:
A. Barley
B. Rice
C. Soybeans
D. Wheat

To determine the correct answer, let's analyze each option in relation to the north China plain:

A. Barley: Barley is not commonly grown in the north China plain, as it is better suited to cooler climates. Therefore, we can eliminate this option.

B. Rice: Rice is commonly grown in southern China, where the climate is warmer and wetter. The north China plain experiences a temperate and semi-arid climate, so rice cultivation is not ideal in this region. We can eliminate this option.

C. Soybeans: Soybeans are a significant crop in northeastern China, but they are not the staple crop of the north China plain. Therefore, we can eliminate this option.

D. Wheat: Wheat is the correct answer. The north China plain has a moderate climate with ample sunlight and fertile soil, making it an ideal region for growing wheat. Wheat has been cultivated in this area for thousands of years and is considered the staple crop of the region.

In conclusion, the staple crop of the north China plain is wheat (Option D).

Now, let's move on to the second question:

To determine why crops grow well on the north China plain, we need to consider the role of the Huang River (also known as the Yellow River) in the region.

The options are:
A. Forms a barrier to animals that eat crops
B. Changes weather patterns in the area
C. Deposits fertile soil after floods
D. Carries pollution away from the fields

To determine the correct answer, let's analyze each option in relation to the role of the Huang River:

A. Forms a barrier to animals that eat crops: The Huang River does not form a physical barrier to animals that eat crops. Therefore, we can eliminate this option.

B. Changes weather patterns in the area: While rivers can influence local weather patterns, the Huang River does not significantly change weather patterns in the area. Therefore, we can eliminate this option.

C. Deposits fertile soil after floods: This is the correct answer. The Huang River is known as the "Yellow River" due to the high amount of sediment it carries from upstream. When the river floods, it deposits a layer of fertile soil known as loess onto the north China plain. This fertile soil is ideal for agricultural production and contributes to the success of crops in the region.

D. Carries pollution away from the fields: The Huang River may carry some pollutants, but it does not serve as a primary mechanism for carrying pollution away from the fields. Therefore, we can eliminate this option.

In conclusion, the correct answer is C. The Huang River deposits fertile soil after floods, which contributes to the successful growth of crops on the north China plain.
