Answer:
Sunlight
Explanation:
Sunlight is not provided 24 hours a day so during nightfall solar panels will not have the ability to collect energy.
Answer:
Answer 1:
Seismic waves, the waves of energy that travel through the Earth as a result of an earthquake can tell us a lot about the internal structure of the Earth because these waves travel at different speeds in different materials. There are two types of waves that travel through the Earth: p-waves and s-waves.
P- waves are faster and they can travel through both solids and liquids. S-waves are slower and cannot travel through liquids. For both kinds of waves, the speed at which the wave travels also depends on the properties of the material through which it is traveling.
Scientists are able to learn about Earth’s internal structure by measuring the arrival of seismic waves at stations around the world. For example, we know that Earth’s outer core is liquid because s-waves are not able to pass through it; when an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive. Similarly, we know that the earth has a solid inner core because some p-waves are reflected off the boundary between the inner core and the outer core. By measuring the time it takes for seismic waves to travel along many different paths through the earth, we can figure out the velocity structure of the earth. Abrupt changes in velocity with depth correspond to boundaries between different layers of the Earth composed of different materials.

Explanation:
Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.
And, when the chemical reaction takes place between the given elements and compounds then they change into products.
For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.
But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.
The remains are called fossils. Fossils are remnants of animals, plants, or microorganisms that have been solidified in the process of fossilization, where the organism is surrounded by sediment, minerals, and other solid objects which are compressed and heated around the organism over time. This forms a solid mass with the preserved organism inside, other known as a fossil.
Humans are the closest relative I think
