Briefly explain how variations in water density can cause horizontal convection currents in sea water.

Geography

4 0

Answer:

Convection currents flow due to variations in the temperature and salinity in seawater, both of which influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.

mafiozo [28]

The town is which I live is Negotino, Republic of Macedonia. The is located in the driest part of the country, so it is very common that there's problems with water during the warmer part of the year. The landscape is mostly dominated by two things, vineyards and barren land which has the characteristics of a is semi-desert, so the town, and the municipality as whole, lacks in wood as well.

My two suggestions for making the town and the surrounding area more sustainable would be:

1. Planting the whole barren land with wild or semi-wild apricots

The wild and semi-wild apricots thrive in this climate, do not need any maintenance, don't have problems with high temperatures and droughts, nor with very low temperatures. From those apricots, the fruits can be used for production of juices and kompots, selling them for much lower prices in the municipality and throughout the country, so the municipality can get a significant income, income that can be used for improving the town's infrastructure and any projects. The shells of the apricots are excellent for heating, thus can be distributed to the households throughout the town as a material for heating during the winter. The trees will also contribute to better air quality and lower the effects of the strong winds.

2. Construction of water collectors

Construction of water collectors will be extremely useful, considering the semi-arid climate in the area. The water collected during the spring and autumn can be used for all sorts of things in the town, thus minimizing, or maybe even eliminating the water problem during the drier parts of the year.

Why do rainforests have high biodiversity?
Ghella [55]

Answer:

Explanation:

Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.

Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.

Bezzdna [24]

Answer:

<u>I and Il only,  crystallization in magma and dissolved in water</u>.

Explanation:

  • Most of the minerals are formed due to the crystallization of lava or molten matter in due course of time when it slowly cools in contact with the land surface as in rapid cooling there is no time for the formation of crystals.
  • Minerals are then formed from the evaporated of the solution a mix of substances dissolved in another. For example deposits of table salts.
  • If the magma erupts to the surface and becomes a lava it tends to cool quickly and small crystals are formed. Depending upon the number of gases and chemical composition of lava.
