Answer: Igneous Rock
Explanation: Radiometric dating is used to date rocks by measuring the decay of their composite materials. Stable isotopes remain the same over time while the nucleus of an unstable or radioactive isotope will decay to form other isotopes
.
Dating rocks using Isotopic methods uses the decay time of the isotope in the rock to assess its age. The accuracy of this method is assured by the fact that when these isotopes decay, they are retained in the rock. Isotopic dating is not very accurate in sedimentary rocks because they contain particles from older rocks.

Explanation:
To date, the majority of neandertal fossils have been found in Europe and western Asia.
There may have been little direct contact between neanderthals and modern humans over thousands of years. They might have contributed to the Neanderthals' impending extinction by preventing them from going back to the areas they liked best.
Around 40,000 years ago, all traces of Neanderthals vanished. The most recent Neanderthal fossils have been found at a few isolated locations in western Europe and the Near East, which was probably the last known location for this early human species.

Factors increasing erosion
Coastal erosion: the strength of the waves breaking along the coastline. Bigger, stronger waves have more erosive power.
Abrasion - rocks carried along by the river wear down the river bed and banks.
Attrition - rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
