<h2>What are fossils?</h2>
Fossils are the remains or impression of plants or animal embedded in rock. They are the remains of dead animals and plants that once lived on this earth in the remote past. Fossils are formed when dead organisms are not completely decomposed.
<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:
There are 110 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids..

Answer:
Q = 8.68 × 10⁴ J
Explanation:
We can calculate the heat required to melt a mass of ice, that is, to change it from the solid phase to the liquid phase, at a constant temperature of 0 °C, using the following expression.
Q = ΔH°f × m
where,
- ΔH°f is the standard enthalpy of fusion (ΔH°f for water: 334 J/g)
Q = ΔH°f × m
Q = 334 J/g × 260 g
Q = 8.68 × 10⁴ J
D- chemical energy
photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy.
Answer: 1169.298 L
Explanation: In order to go from grams to liters, you must find the moles first using the molar mass, 62.068 g/mol (found via google search). I will assume the ethylene glycol is in gas form so we can use the 22.4 L per mol conversion.
Using dimensional analysis, starting with the kg, we must convert to grams, then moles, then liters.
Multiply the top individually, then the bottom individually.
Divide out.
In the end, we get 1169.298 L of ethylene glycol.
