kow [346]

<h3><u>The following events are identified as chemical weathering:</u></h3>
  • The minerals in a marble statue react with water to form acids and pores in the structure.
  • The rocks in a region are streaked orange after being exposed to repeated rains.

<em><u>Reason: </u></em>

When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.

In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.

<h3><u>The following events are identified as Mechanical weathering:</u></h3>
  • A piece of rock crumbles after being constantly thrashed by strong waves.
  • Industrial runoff forms cracks in a rocky structure in its path.

<em><u>Reason:</u></em>

When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.

In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.

Why do scientists study fossils?
Tasya [4]
Hi,

By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.

Option c) is the correct option above.

<span>c) Fossils give information about the time period in which organisms lived in the past.
