Explanation: Nucleation can be described as the process that determines how long an observer has to wait before a new phase occurs,such as the conversion from liquid to gas or vapour or from Solid to liquid.
There are basically two types of Nucleation which includes the HOMOGENEOUS NUCLEATION AND THE HETEROGENEOUS NUCLEATION.
Homogeneous nucleation(nucleation that occurs in the absence of foreign particles) is a type of Nucleation that requires more undercooling than Heterogeneous nucleation, they occur below the freezing temperatures.
Heterogeneous Nucleation (a type of Nucleation that occurs in the presence of foreign particles), it usually takes place at the surface and they usually require less undercooling temperature than Homogeneous nucleation.
Answer:
<u><em>Sediment A: </em></u>
- Carbonate sand
- Sediment made of seashell and calcite
- Sediment that has travelled farther
<u><em>Sediment B: </em></u>
- Quartz sand
- Made of harder minerals
- Forms when rocks break apart
Explanation:
<u><em>Sediment A</em></u><em>:</em> In the figure shown on left, the particle size is small and corners are round. This suggests that it is most likely made up of carbonate which can dissolve easily in the presence of water and CO2 forming weak acid (carbonic acid). Likewise, it is also possible that the material has traveled longer distances and due to erosion, the corners of the particle has become rounded. The carbonaceous material in the sea environment is often made by carbonate producer organisms that use calcite to make the protective shell.
<u><em>Sediment A</em></u><em>: </em>In the figure shown on right, the material is bigger in size with hard and sharp corners. This means that it is either broken recently from the rock and has not traveled longer distances OR, it is made up of harder minerals that cannot break easily by weathering and erosion process. Quartz sand has such properties.
