How does very rigid soil respond when struck with a 1 kg hammer?

When very rigid soil is struck with a 1 kg hammer, it is characterized by its high density and strength, which means that it does not easily deform or rupture under impact. Rigid soils, such as hard clay or consolidated materials, have particles that are tightly packed and bonded together, making them resistant to sudden forces.

In this scenario, the 1 kg hammer does not generate enough force to overcome the structural integrity of the rigid soil. Instead of rupturing, the soil remains largely unchanged because of its inherent strength and cohesiveness. This is a key concept in geotechnical engineering, where understanding the mechanical properties of soil helps in predicting how it will behave under different loads and impacts. Thus, the response of very rigid soil to the hammer strike aligns with the description of it being incapable of rupture under the specified conditions.
