there are 3 rock types:(a)igneous,(b)sedimentary,(c)metamorphic.If rock (a)were to cut across both other rocks and (c) is the oldest rock, describe the new relationship between the rocks.
are you doing 103 by any chance im stuck on this q as well and thought it might be asking for a diagram like page 127
what do you think
I am doing s103 and have been thinking along the lines of a similar diagram.
In order to describe the new relationship between the rocks, we can create a diagram to better understand the scenario.
First, let's label the three rock types:
- Rock (a): Igneous
- Rock (b): Sedimentary
- Rock (c): Metamorphic
According to the given information, Rock (a) cuts across both Rock (b) and Rock (c), and Rock (c) is the oldest rock.
To represent this visually, we can draw three horizontal lines, each with a label for the rocks, arranged from oldest to youngest:
Rock (c) Rock (a) Rock (b)
|______________|
Now, since Rock (a) cuts across both Rock (b) and Rock (c), we can represent this by placing a diagonal line crossing through both Rock (b) and Rock (c) from left to right.
Rock (c) Rock (a) Rock (b)
| |
|___________|
Therefore, the new relationship between the rocks can be described as follows:
Rock (c) is the oldest rock, followed by Rock (b), and the youngest rock is Rock (a). Furthermore, Rock (a) cuts across both Rock (b) and Rock (c).
