Earthquakes are the result of physical changes. As the tectonic plates located At Fault lines grind past each other, tension is released in an elastic rebound and an earthquake occurs.
No, the excavation of soil is a mechanical operation.
It's a religious change. It revolves around Jesus.
Excavation of earth is a mechanical operation, hence it is physical not chemical property.
Earthquake is a tectonic phenomena instead of a physical process.
A physical, because the tsunami isn't changing water's chemical properties. In other words, it is still the same substance.
Both physical and chemical changes occur on and within Earth.
Digging is a physical activity
Physical Change.
chemical
Ice wedging would help slow chemical weathering and make the soil more fertile.
Soil is a chemical solution of metals
Mostly on farmland because of chemical fertilizers, which over several years will tend to acidify the soil somewhat. That is why farmers "lime" their fields every few years.
Chemical change: when additives such as pesticides or household cleaners change the pH of soil and water. Acid rain is also a chemical change.Physical change: Forest destruction and the installment of housing developments are both examples of a physical change in the environment.
A chemical change is a chemical reaction.
The word you are looking for may be "excavating".
Ice wedging would help slow chemical weathering and make the soil more fertile.
I'm 13 and I know for a fact that soil erosion is physically changed.
It's possible to reverse the change. All you need to do is seperate the sand and the soil. No chemical bonds were altered or anything.
chemical change
chemical soil
In civil engineering, excavation is a process whereby rock or soil material is removed from the ground usually forming a void or hole.
Soil is a chemical solution of metals
physical
If you think to "soil" this hasn't a chemical formula or equation. This soil has a pH over 7.
Unless it were to suddenly go up in flames..... Definitely a physical. Just take a breath and think about it! These are easy points!
too much water Lack of nitrogen in the soil
