Answer:

The two subcategories of igneous rocks are intrusive and extrusive igneous rocks.

Explanation:

The igneous rocks are the rocks that form from cooling magma and lava. They are the base for the formation of the two other types of rocks. The igneous rocks are divided into two subcategories, intrusive and extrusive.

The intrusive igneous rocks are the ones that form from magma that didn't manage to come out on the surface but gradually cooled off into the crust. The extrusive igneous rocks are the ones that have formed from lava that cooled off and that has come out on the surface or very close to the surface.

Because the extrusive and intrusive rocks take different times to form because of the difference in temperature and pressure on the surface and deep into the crust, they have differences in their appearance. The most noticeable difference is that the intrusive igneous rocks have coarse grains, thus large and well-defined ones, while the extrusive ones have fine grains, thus very small and almost unnoticeable.

despite of many benefits, aquaculture is actually not considered a sustainable activity in the perception of the scientific comm
Diano4ka-milaya [45]

Answer:

Aquaculture has been considered as an option to cope with the world food demand. However, criticisms have arisen around aquaculture, most of them related to the destruction of ecosystems such as mangrove forest to construct aquaculture farms, as well as the environmental impacts of the effluents on the receiving ecosystems. The inherent benefits of aquaculture such as massive food production and economical profits have led the scientific community to seek for diverse strategies to minimize the negative impacts, rather than just prohibiting the activity. Aquaculture is a possible panacea, but at present is also responsible for diverse problems related with the environmental health; however the new strategies proposed during the last decade have proven that it is possible to achieve a sustainable aquaculture, but such strategies should be supported and proclaimed by the different federal environmental agencies from all countries. Additionally there is an urgent need to improve legislation and regulation for aquaculture. Only under such scenario, aquaculture will be a sustainable practice.
