The part of the experiment in which the experimental factor has been removed is referred to as <span>the independent variable. </span>The dependent variable<span> is the element which is being measured in an experiment or evaluated in a mathematical equation.</span>
There are two main<span> types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.</span>
Explanation:
The discoveries indicates that the rocks were formed over millions of years ago due to the age of fossils they contain.
Fossils are the preserved remains of life found in rocks. Most fossils are used in relative dating of rocks.
- Dinosaurs are extinct organisms that once lived in the Mesozoic. This was about 100 million years ago.
- Tool man also grazed the surface of the earth just a few thousands to a million years.
- We are able to find their fossils in rocks because they have lived in some certain geologic periods.
- Here we are using the fossils to date the rock and this is called relative dating
