Answer: The geologic time scale is the “calendar” for events in Earth history. It subdivides all time into named units of abstract time called—in descending order of duration—eons, eras, periods, epochs, and ages.
Explanation: I learned about it the other day
Answer:
Heat causes the molecules to move faster (heat energy is converted to kinetic energy), which means that the volume of a solid or a liquid. ... The particles in the air do not have more kinetic energy than particles in the mercury, because they are the same.
Explanation:
I hope this help you!
I am pretty sure the answer is D
When a volcano erupts it releases a large amount of dust, smog, rock, and other materials. Basically, these bits and pieces float to form a metaphorical dust cloud. These clouds can often block out the sun like an ordinary cloud; however, because the cloud is dark, even less sun will be able to get through. So because the sun can't reach the ground, the temperature might decrease.
when the thermal energy is the energy contained within a system that is responsible for its temperature.
and when the thermal energy is can be determined by this formula:
q = M * C *ΔT
when q is the thermal energy
and M is the mass of water = 100 g
and C is the specific heat capacity of water = 4.18 joules/gram.°C
and T is the difference in Temperature = 50 °C
So by substitution:
∴ q = 100 g * 4.18 J/g.°C * 50
= 20900 J = 20.9 KJ
