How may the chemical make-up of a 200-year-old fossil differ from the chemical make-up of a 100- year-old fossil?

Answers

Answer 1

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

Answers

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.

During which phase of the moon do neap tides occur?
O full
O gibbous
O new
O quarter

Answers

Answer:

D

Explanation:

quarter

During the quarter phase of the moon, neap tides occur.

What is the phase?

The phase of a periodic function F of a real variable t in physics and mathematics is an angle-like quantity that denotes the percentage of the cycle that has been completed up to t. It is given the notation phi and is scaled in a way that changes by a complete turn as the variable t cycles through each period.

Since the neap tides happen when the sun and moon are at a straight angle, the earth's gravitational pull is at its weakest at this location. As a result, we will depict the moon in various angular relationships to the earth and identify it appropriately using the available options.

The first and third halves of the moon, when the moon seems to be "half full," are when neap tides occur. Because of the moon's and sun's positions, astronomical considerations are taken into account by NOAA when predicting tides and tidal currents.

Therefore, Thus option (D) is correct.

Why is the land breeze experienced at night?
need an explanation related to the following diagram

Answers

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.
