Alex73 [517]

Incomplete question. The remaining part reads;

Choose the correct words or phrases to complete the sentences.

Global winds occur due to

1. Choose...

a. solar currents

b. convection currents

c. sea breezes

d. uneven heating

over a large area and this forms

2. Choose...

a. solar currents

b. convection currents

c. sea breezes

d. uneven heating

caused by cool and warm air.

Answer:

1. d. uneven heating

2. b. convection currents

Explanation:

1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.

2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.

STatiana [176]

Answer:

The properties that do not vary with the variation in the quantity of the material are called as intensive property.

While the extensive properties are those which vary with the variation in the quantity of the material.

Intensive properties:

Mass and volume

Extensive properties:

Density and melting point

Explanation:

The properties that do not vary with the variation in the quantity of the material are called as intensive property.

While the extensive properties are those which vary with the variation in the quantity of the material.

Intensive properties:

Mass and volume, as with increase in quantity of the material mass and volume increases.

Extensive properties:

Density and melting point, as they remain constant for a object or material

What are the costs and benefits of using solar energy

fiasKO [112]

Advantages
Solar energy is a clean and renewable energy source.Once a solar panel is installed, solar energy can be produced free of charge.Solar energy will last forever whereas it is estimated that the world’s oil reserves will last for 30 to 40 years.Solar energy causes no pollution.Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical.Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them.In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.

Disadvantages
Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments.Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate.Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build.Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time.
