Answer:
In the history of agriculture, no technology has been adopted so quickly and completely as genetically engineered crops. Particularly useful crops are ones that have an engineered resistance to herbicides. These crops have alluring benefits: reduced crop damage when herbicides are sprayed, easier weed management, and even the potential for environmental benefits. So what’s the problem? Herbicide-resistant weeds. The benefits gleaned from these crops begin to disappear as these superweeds gain prominence on farmlands across world. However, to fully appreciate the current predicament, it is necessary to understand what led to the difficult problem of superweeds. And it starts with the most common herbicide used in agriculture: Roundup.

Answer:
They are deposits of silt and mud carried by the wind.
They are found in regions close to but outside areas of glaciation.
There are deposits in Europe, North America, China, and Argentina.
Explanation:
Loess was first discovered and coined in Europe and refers to an important component of the soils of the European Plain. Loess consists of particles of silt, clay, and mud that have been carried by the wind and eventually deposited to form extensive formations.
Loess layers are not only deep but also conducive to agriculture as they are also fertile. Perhaps the most common source of loess is the glacial activity since the movement of glaciers produces a large amount of finely ground sediment on the fringes that is later picked up by the wind.
