<h3>2.
Fossil record</h3>
The fossil records are referred to as the totality of fossils. It helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era. Fossil records can be used to show that organisms changed to meet new conditions
<h3>3. The grand staircase</h3>
The Grand Staircase is referred to as a sequence of sedimentary rock layers that stretch south for 100 miles from Bryce Canyon National Park through Zion National Park and into the Grand Canyon.
The different environmental conditions the Grand Staircase exposed to over this +1 Billion year is heat
4. Based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.

Answer:
2. Copper (II) carbonate plus sulfuric acid produces copper (II) sulfate and carbon dioxide and water.
- We need the "II" after copper to specify what charge it is. It's +2 because carbonate is -2.
3. Calcium hydroxide plus carbon dioxide gas produces calcium carbonate and water.
Answer: The energy of a mole of photon associated with this frequency is 
Explanation:
The energy and frequency are related by :
E = energy of photon
N = number of moles = 1
h = planks constant = 
= frequency = 
The energy of a mole of photon associated with this frequency is
