Which factor prevents us from finding precambrian fossils?
Most rocks from that era are deeply buried.
What are two forces that can expose deeply buried fossils?
Erosion
What prevents us from finding precambrian fossils?
Most rocks from that era are deeply buried.
Slope mining is used for deeply buried mineral deposite?
No, if the minerals are deep, slope mining is not possible.
Which is a factor that prevents us from finding the Precambrian fossils?
most rock form that era are deeply buried.
What happens to snow that is deeply buried?
It ends up getting very compact and cold and hard to break up
Example of summary?
Precambrian rocks have been so deeply buried that they have changed by heat and pressure. That's a summary about the Precambrian time.
What time of year is geothermal energy produced?
The idea behind geothermal energy is that the pipework for it is buried deeply enough that the temperature is constant year-round.
What rock would form if sandstone was deeply buried and had heat and pressure making it recrystallize?
The metamorphic rock quartzite would form due to the heat and pressure.
Can the temp of earth change a rock?
Yes, rocks deposited near the surface (eg limestone) are changed by the pressure and heat when they are buried deeply in the earth (eg limestone becomes marble)
Why dont rocks deform under confining stress?
a deeply buried rock is pushed down by the weight of all material above it. Since the rock cannot move, it cannot deform.
How much time need a cat to be decomposed?
There is no way to answer this, as it depends on many factors, such as the soil in which it is buried, and how deeply, if it is buried at all. Some bodies have been found virtually unchanged, for instance, after thousands of years buried in a peat bog. Left on the surface but untouched by scavengers, it is likely that something as small as a cat would last perhaps a month. Buried three to six feet in clay, it is more likely that it would not decompose for a year or more.
