How may the chemical make-up of a 200-year-old fossil differ from the chemical make-up of a 100- year-old fossil?
Answer: It depends on the degradation process and layers of strata above the fossil.
Explanation:
The fossil deep beneath the 100 year old strata is expected to contain more amount of mineral content because of the deposition of dead and decaying matter. The chemical conformation of the organism will remain within the upper few layers of the strata, which can be used to analyze the chemical makeup of the organism but the chemical make up is less likely to be traced from organism whose fossil was 200 years old. As the organism is degraded and decomposed to an extent that few traces are likely to be expected which can be used to trace the chemical composition.
Canada makes pollution but has huge amounts of forest.
1/Economic deficit
2/Ecological deficit
3/Economic reserve
4/Ecological reserve
Answer: 4/Ecological reserve
Explanation:
Ecological reserves are those places which maintain a natural balance of abiotic and biotic resources. Examples are forests, wild life sanctuaries, national parks, and others. These are rich source of biodiversity as these areas are restricted to be affected by the human population. Also the large number and diversity of vegetation is capable of absorbing carbon dioxide, carbon monoxide which is a chief pollutant gas released from automobiles, household chimneys, and industrial gaseous discharge.
Thus Canada forests are ecological reserves which absorbs the pollution from different sources thus they purify the air.

Why is the land breeze experienced at night?
need an explanation related to the following diagram
Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches. ... The movement of the wind is a result of differences in air pressure over the land and the ocean. Warm air is less dense and rises, therefore cool air is more dense and sinks. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
