The rocky ledge has been eroding at a rate of about 1.3 m per year for nearly 9,900 years.

How many kilometers has the ledge been eroded in the last 9,900 years? How many kilometers has the ledge been eroded in the last 9,900 years? Slide 5 Deposition Rates If 30 cm of sediments are deposited every 1,000 years, how long would 10 m of sediments take to accumulate?

If 30 cm of sediments are deposited every 1,000 years, how long would 10 m of sediments take to accumulate? Slide 6 Varve Count Generally occur in glacial lakes. Sediments will deposit based on seasonal patterns.

Pebbles and coarse sediments in spring and summer, clay and fine particles in winter. Sediments will deposit based on seasonal patterns. Pebbles and coarse sediments in spring and summer, clay and fine particles in winter. Slide 7 Radiometric Dating Radioactive isotopes have nuclei that emit particles and energy at a constant rate regardless of surrounding conditions. Slide 8 Half-life The time it takes half the mass of a given amount of a radioactive parent isotope to decay into its daughter isotopes.
