Question 3

TALLEST NOT HIGHEST

Answer 3

Did

Question 4

What happens during Radioactive decay

Answer 4

Eco

Question 5

Define parent isotope, daughter isotope, an shelf life

Answer 5

Eco

Question 6

What happens during radioactive decay

Answer 6

Atoms can go through Alpha decay, Beta decay, or Electron capture. In Alpha decay, an alpha molecule (2protons and 2 nuetrons) are removed from the atom. In Beta decay, an electron is removed, converting a nuetron is into a proton. Electron capture is the opposite. An electron is absorbed by the nucleus converting a proton into a nuetron. Any of these processes converts a parent atom into a daughter atom.

Question 7

Parent Isotope vs. Daughter Isotope

Answer 7

Parent Isotope is the original isotope. Daught isotope is an isotope whose number of protons or nuetrons have been altered–changing the atom

Question 8

relative proportions

Answer 8

This is how scientists date rocks. As time goes by the amount of parent isotopes goes down and daughter isotopes go up. After about a dozen 1/2 lifes, its difficult to tell age. One half life occurs when half of the parent isotopes have become daughter isostopes.

Question 9

Nonconformity

Answer 9

boundary between two different rock types

Question 10

Angular Nonconformity

Answer 10

boundary between two different sequences of sedimentary rocks, one of which has been tilted on an angle by plate tectonics or local faults.

Question 11

Disconformity

Answer 11

a gap of time between two sequences of sedimentary rocks.
