Fossils represent the animals or plants that were living at a certain time, and can be used to age rocks.
Answer:
Explanation:
Biomass refers to the organic matter from plants and animals.
It is also a source of renewable energy which can be used to produce electricity.
Energy from biomass orginates from the process of photosynthesis where green plants manufacture food for the ecosystem using carbon dioxide and sunlight.
Biomass has the following use:
It is widely available: Biomass can easily be sourced for. It is widely abundant in the environment.
It is inexpensive: Due to its wide availability, its source materials are very cheap and lies readily in the environment when we compare this to exploration for fossil fuels and mining for uranium.
It is carbon neutral: Since biomass constitutes a part of the carbon cycle, energy from biomass does not lead to climate change. Green plants use carbondioxide to manufacture their food and it is released back to the atmosphere when biomass is tapped.
It is environmentally friendly: The use of biomass as a source of energy does not affect the environment negatively. It is a clean source of energy.
It helps to reduce amount of waste: biomass energy helps us put wastes into a very good use.

Answer:
Cobble is a big piece of stone whereas clay is the smallest particles of earth.
Explanation:
Cobble is a small round stone used to cover road surfaces. Pebbles are the round rock fragment with a diameter of 4-64 mm which is smaller than a cobble but larger than a granule. Sand is a loose granular material that produces from the disintegration of rocks, the particles of sand is smaller than gravel. Its particle size is 0.0625 to 2 millimeters. Silt is granular material having a size between sand and clay about 0.002 to 0.05 mm. Clay is a stiff, sticky fine-grained particles that can be molded when present in wet condition and is used to make bricks, pottery, and ceramics. Clay particles are smaller than 0.002 mm in diameter.
