Section 200.22 Program standards for behavioral interventions. Behavioral interventions for students with disabilities shall be provided in accordance with this section and those other applicable provisions of this Part and/or Part 201 that are not inconsistent with this section. (a) Assessment of student behaviors.
The age of Earth was calculated to be about 24-40 million years based on the laws of thermodynamics. Unknown at the time was that the Earth has an internal heat source (radioactive decay) In 1899, John Joly (Irish) calculated the rate of delivery of salt to the ocean.
2 things scientists must measure to find the age of a rock. the amount of radioactive element in a mineral in a rock and the amount of the stable element into which the radioactive element decays. by calculating the ratio of the radioactive element to the stable element can scientists determine the age of a rock.
