How are volcanoes and earthquakes linked to plate tectonics?

First, you have to understand what convection is.

Did you know that the hotter something, the more it expands? This happen because heat, at an atomic level, is nothing but vibration. If a liquid is hot, it means that there is more vibration between it's atoms. And, more vibration causes to have more space between the atoms, which causes the density to decrease.

So, when a liquid has it's top cold, and it's bottom hot, the top will be more attracted by the gravity than the bottom, because it's more dense. This will cause the top to want a lot to get down, and the bottom, because of the pressure of the top, will want to go up. This will cause a spiral movement; the bigger the difference, the faster and the more violent this spiral movement will be (and that's what causes hurricanes)

So, what this has to do with Earthquakes and stuff?

The Earth, when it was formed, was really, REALLY hot. It has being losing it's heat ever since, but, since there is not air in the space, it can only lose it's eat though radiation, which is <em>very  </em>slow. And also, the bigger something is, the slower it cools down, because there is more vibration, more movement, more energy to be lost. The earth was formed 4,5 BILLIONS of years ago. That's A LOT of time. But the lost of heat by radiation is so slow, and the earth has so much heat to be lost, that it still didn't cool down that much.

You can think of Earth like a hot potato that got out of the oven just a little ago; the outer part is already cold, but just take a bite, and you will see how HOT it's insides are. You can't take a bit out of earth, of course, but it's insides are a lot hotter that the outside, because it's the outside that loses eat. The insides have to wait for the outsides to cool down, and then lose eat to the outside.

So... we got a planet that's really hot in the inside, so hot that it's mantle is made out of liquid rocks!

So, now, it's the time to connect the dots: the upper part of the mantle loses heat faster than the inner one. This causes a spiral movement, and, since the tectonic plaques are floating in this liquid, they move as well!

When two plaques move one against each other, they crash against themselves, and this causes an earthquake. If they move away, this creates an open space; and since the liquid of the mantle has, like, THE WHOLE CRUST OF THE PLANET CRUSHING IT, the mantle is craving to get out, so when there is an opening, it squirts out like crazy, creating an eruption. After a while, the magma solidifies, creating a volcano.

Volcanoes are caused most the time by tectonic plates moving and so are earthquakes, the tectonic plates slide and move to cause the tremor!

3 physical factors which determine the type and density of forests.
Anna007 [38]

Explanation:

The physical environment of forests is determined by edaphic (soil) factors and micro-climate (precipitation, light, temperature, and wind). Gas-exchange within forest canopies depends upon the microclimatic condition within the forest, as well as, edaphic factors and water availability.

In Ontario, what type of land use should be given priority: agriculture, recreation, conversion, or residential usage? Explain w
Nana76 [90]

Answer:

Residential land use should be given priority in Ontario.

Explanation:

Ontario is the most populous province in Canada. Its approximately 15 million inhabitants make up 40% of the country's total population. Within the province is Toronto, the most important city in Canada, as well as Ottawa, the national capital, and other important cities such as Hamilton or London, among others.

Ontario is, in essence, Canada's economic engine. Its largest production is industrial, with different industrial and technological poles spread throughout the province. For example, in the city of London, the main industry is automotive production, while in Hamilton there are a large number of steel industries. Not minor are the energy, banking, financial and even agricultural industries in the province.

All this enormous production makes more and more labor want to move to the province, so it is necessary to expand the residential areas in order to receive all these workers and thus facilitate the expansion of Ontario's economic production.

Match the climate zone in column 1 to the characteristic in column 2.
Aliun [14]

The correct matches are:

- A. Tropical - On the Equator;

- B. Dry - Near the Equator;

- C. Moderate - Mildest weather;

- D. Continental - Severe temperature changes;

The climate types differ from one place to another on our planet, and in general they are separated in zones in accordance to the latitude at which they are.

The tropical climate is the one that lies on and around the Equator, and it is warm and wet for the whole year. Little north and south of the Equator we encounter the dry climates, where the landscape is occupied by deserts, with extremely high temperatures, and very little precipitation. Further north come the moderate climate types and the continental climate types, they are similar to each other, but the temperatures in the moderate climates have less variation, while in the continental ones it is much bigger, also the moderate ones have more precipitation, and the continental ones have less precipitation. They are both in the mid-latitudes.
