Can geologists use radioactive dating to find the absolute ages of sedimentary layer A B C D and E?
yes because its a rock
What the difference between clastic and chemical sedimentary rock?
The chemical sedimentary rock will not be composed of cemented rock particles.
How does sedimentary rock become a metamorphic rock?
Sedimentary rock can be metamorphosed by: a) exposure to heat by close proximity to a heat source such as a plutonic intrusion; b) from deep burial pressures; c) from directed pressure and heat from mountain building processes; d) chemical changes from exposure to heated fluids, the fluids heated by a plutonic intrusion. Metamorphism of sedimentary rocks can result in a realignment of mineral constituents, recrystallization, or new chemical compositions. .
What types of materials erupt from valcanoes?
magma and sedimentary rocks. :D as well as some of the molten rock around the volcano that break off as a result of the eruption.

A band of the element iridium found world-wide in sedimentary rock of the same age may indicate?
that an enormous meterotie struck the earth and played some role in the cretaceous extinction.
What the difference between clastic and chemical sedimentary rock?
The chemical sedimentary rock will not be composed of cemented rock particles.
What is volcanoes crust?
The volcanoes crust is what we live on! Its the outer most layer of Rock. :D
What kind of rocks are formed by wind erosion?
Sedimentary rocks are formed from chemical and physical weathering of rock, their subsequent erosion and transportation to a place of deposit, and their lithification through compaction and cementation.
