Answer:
<u>Relative dating </u> determines the order of layers of rock based on their relationship to one another .
Explanation:
Relative dating -
The method to determine the relative order of the past events , without finding the absolute ages .
The actual numerical dates of the rocks are not provided by this method .
Even the order of the series of the past is determined by this method , not when the event occurred .
The preferred method in paleontology is done by relative dating by biostratigraphy , and is very accurate .
The first one is D
The second is B I think
Answer:
A volcano is a opening on the surface that allows material warmer than what is on the surface to erupt and come out of the hole
Explanation:
The approximate distance between points A and B is 10m.
The cleavage of a silicate mineral is largely determined by internal structure
A silicate is any member of the family of silicon and oxygen containing anions, typically represented by the generic formula [SiO(42x)4x]n, where 0 x 2. Orthosilicate SiO4 4 (x = 0), metasilicate SiO2 3 (x = 1), and pyrosilicate Si 2O6 7 (x = 0.5, n = 2) are members of the family. Any salt of these anions, such as sodium metasilicate, or any ester having the appropriate chemical group, such as tetramethyl orthosilicate, are likewise given this designation.
