1. Sources of Ocean pollution: There are different sources of ocean pollution, oil spills; waste dumping and toxic wastes are just few of them. Agricultural runoff and plastics are also play a major role in ocean pollution.
2. Developmental activities and ocean pollution: A lot of developmental activities are always take place near oceans like construction, mining, fisheries, tourism and aquaculture, which leads to ocean development.
3. Ocean gyres: Plastics and other materials are discarded in oceans; these wastes concentrate in some areas, which are called as gyres. The North Pacific Gyre is larger than the American State Texas.
4. Threat for ocean life: Toxic wastes accumulate in the body of marine life and when these animals are consumed by human, they cause different kinds of diseases. In some cases, deaths can also occur.
5. Prevention: Limiting the recreational activities in oceans and putting a ban on waste dumping in oceans can reduce the ocean pollution to some extent. Moreover, authorities should make sure that only treated water is dumped into the oceans.

1. Definition

Crystals are such solid materials in which atoms and molecules are necessarily arranged in regular or well-defined and repeating pattern. All crystals have a common specialized feature which is the flat surfaces of surfaces. Salt crystals, diamond, rubies, emeralds, snowflakes and quartz are some common types of crystals.

2. Crystallization

Crystallization is the name of crystal formation process which occurs naturally. In crystallization process, the liquid cool down and then solidify slowly. If the rate of solidification is such that, the molecules and atoms arrange themselves in regular pattern, the resultant substance is called crystal.

3. Shapes of Crystals

The liquid could solidify in either shape during crystallization, but the common shapes of crystals are seven. These shapes are trigonal, hexagonal, cubic, triclinic, orthorhombic, tetragonal and monoclinic.

4. Rocks

Rocks are the largest naturally existing example of crystals. Rocks are mostly formed by cooling down and slowly solidifying the magma.

5. Diamonds

Diamonds are an interesting example of crystals, as they consist of only one molecule made by repetitive orientation of lots of atoms.
