No it is not true all rocks can be dated radiometrically. You need special minerals that do not add or loss elements easily during the different processes that a rock may under go.
yes it is true
no. Extrusive rocks are usually have bigger crystals and a rougher texture, unless you notice obsidian and another type of extrusive rock don't have crystals, at all
no, there are more rocks
no
Not all rocks are, only sedimentary rocks are truly made up of sediments. Some metamorphic rocks do because they are formed when heat and pressure are applied to sedimentary rocks, which makes sediments the basis of these rocks as well
yes it is true
they contain atoms
They all slowly absorb CO2 from the atmosphere
Yes m that it true, other than glasses all rocks have grains.
Yes, mainly, they will rust
false
no..... not at all..... the movie was completely fake.
No, carbon dating is not used to date index fossils. Carbon dating is only effective on organic materials up to about 50,000 years old, while index fossils are used to identify the age of rock layers and are typically much older. Index fossils are dated using relative dating techniques based on their position in the rock layers.
A is false - Rocks are composed of minerals not the other way round. B, C and D are all true.
But there are. The Earth is about 4,600 million years old, the oldest known rocks are to be found in northern Quebec, Canada and are dated at about 4,280 million years. They were only found 2 years ago so perhaps even older rocks could be found.
no. Extrusive rocks are usually have bigger crystals and a rougher texture, unless you notice obsidian and another type of extrusive rock don't have crystals, at all
tha'ts not true at all even i know that hahaha it has to do with earth science not whatever you're talking about.
