The answer to your question depends on the type of earthquake it is. For instance, there is something called P-waves which are waves that move rapidly from the Earth's layers before an earthquake or any other phenomenon like a volcanic eruption occurs. If the earthquake is big, then its p-waves are also higher which means we may be able to hear it. If the earthquake is small, then the p-waves are also low, meaning we won't be able to hear it.

I hope I was able to help you! :)

Yes, it is, but the semi-truck passing by is usually only seconds before the shaking starts. Animals are a lot more sensitive to low frequency sounds than humans are. Many animals start leaving the area of an earthquake epicenter because they can probably sense or hear the movement or the rocks as the stresses and strains on the rock build up and reach the stress capacity and strain limits that the minerals in the rocks start to fracture, which is what causes/initiates the earthquake. Sound, seismic P-waves, and surface Rayleigh and Love waves, travel through solids (rocks and liquids) faster than sound in air travels. Animals leaving hours or even days before a large Richter magnitude earthquake is well-documented.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
