String a piece of twine between the cups. Use a long piece of string to help the sound travel farther. Tie a knot in the end of the string to keep it in the cup. Decorate the cups if desired. One person can hold the phone up to their ear and the other person can talk into the other cup. Keep the string tight or the sound waves won’t travel.
Explanation:
Answer:
The inner core is the Earth's "interior".
P-waves pass through both the mantle and core, but are slowed and refracted at the mantle / core boundary. Whereas, S-waves pass from the mantle to the core and are absorbed due to shear waves being incapable of transmitting through liquids. Therefore, this is (further) proof the outer core does not behave like a solid substance.
Answer:
A. Rock fragments are layered and pressurized over time.
Explanation:
Sedimentary rocks are derived from pre-existing rocks that have been subjected to agents of denudation, weathered, transported and deposited within a basin.
In the basin, the sediments are accumulated in their final resting position.
- Sediments are accumulated as layers on top of one another.
- The pressure of the sediment on top of another forces out water and presses the layers into sheets.
- Over time, the compression leads to lithification of the rock.
- During lithification, compaction and cementation occurs.
