Hi,
Scientists have used rock samples to date the Earth's past. They also might use Steno's principles.
Relative dating is the determination of the age of a rock or geological event by comparing with other rock/ geologic events. Absolute dating is a form of geologic dating that gives an actual date or age in history that the item was formed or died in years.
Steno's principles are:
Law of superposition - Bottom layer is the oldest, top layer of the youngest In undisturbed layers of sedimentary rock or magma.
Original horizontally - When sedimentary rock layers form, they are "created in a horizontal form.
The Principle of Lateral Continuity -<span> States that layers of sediment initially extend </span>laterally<span> in all directions.

Type of Erosion Control<span> </span>Pros of Using this Control
- Jetties - protect buildings on beaches from losing sand
- Breakwaters - Stop the waves from hitting the beach
- Beach Renourishment - easy way to prevent sand erosion
- Planting of dune grasses and plants - roots hold sand together and make it more difficult to wash away
Cons of Using this Control
- can seriously affect the tidal circulation and the health of wetlands
- changes profile of the beach
- can cause bottom organisms and habitats to e smothered by muddy water
- can make the beaches difficult to use for recreation
<span>Paragraph:
</span> I think that Breakwaters<span> are the best to use. One reason is the only major con that is has is changing the profile of the beach instead of harming wildlife and taking away funding (recreational use.) Another reason is that the rocks used provide great climbing tools for beachgoers and might entertain them. A third reason is that breakwaters can be underground as well, not damaging the beach very much. Finally, they save millions of dollars in replacing sand.</span>
It depends on the cave , but usually c<span>) chemical sedimentary rock</span>
Well if you want to be technical, than Ferdinand and Isabella were since they were king and queen.
But <span>Tomas de Torquemada was the general.</span>
