What does plate tectonic theory describe?

Answers

The theory of plate tectonics, explains how the movement of geologic plates generates earthquakes, volcanoes, and mountain formation, transformed the field of earth sciences. Plates generally are of 2 types i.e. oceanic and continental.

What is Continental drift ?

One of the earliest hypotheses put up by geologists for how continents might migrate through time is called continental drift. The science of plate tectonics has now supplanted the theory of continental drift.

The scientist Alfred Wegener is most closely connected with the concept of continental drift. Wegener wrote a paper outlining his notion that the continents were "drifting" across the Earth, occasionally crashing through oceans and into one another, in the early 20th century. Alfred Wegener called it continental drift.

Plate tectonic theory generally states that there are generally 3 types of movements in plates convergence, divergence, and transformation. By each movement there is some landform generation is taking place. Depending upon the plate type and movement type.

Hence, theory of plate tectonics, explains how the movement of geologic plates generates earthquakes, volcanoes, and mountain formation, transformed the field of earth sciences.

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. ... The lithosphere includes the crust and outer part of the mantle.

Why must countries trade with each other

Answers

Countries trade with one another to receive a variety of items, therefore, the markets have many different brands to sell, and the customers have many choices. Also because some countries do not have the resources and need them, so they trade some of their unique resources with another countries resources. 
Countries must trade with each other in order to gain resources that they don't have. Look at petroleum for an example. Americans have excavated all the oil that's in the states, but since we rely so heavily on gasoline to simply function, we buy and trade with the middle east for the petroleum they have there. That's why its so important to keep good relations with the Middle East simply because we rely so heavily on them for this good.

At the beginning of the day, it was -5°. throughout the day, the temperature increased 19°. what was the temperature (in degrees) at the end of the day?

Answers

Answer: 14

Explanation:

If it was -5 degrees throughout the day, and the temperature increased a positive 19, it would be -5 + 19.

We know that the answer is positive, since the positive number is bigger than the negative number. But since it is, the negetive number subtracts from the positive. So we have to switch the numbers around.

19 - 5 = ?

-5 + 19 is the same as 19 - 5.

19 - 5 = 14

which plate boundary and movement commonly creates volcanoes that can result in the development of habitable islands?

Answers

Constructive plate boundaries
1) Convection currents in the mantle move the plates
2) 2 plates of oceanic crust diverge/pull apart e.g. North American and Eurasian plates.
3) The rising magma forces the ends of the plate to push up and buckle. This creates tensional cracks on the underside of the plates.
4) Magma is squeezed into the gap between the two plates and is cooled by the ocean to form new, solidified rock/basalt.
5) Rising magma forces its way through the tensional cracks and forms sub-marine shield volcanoes on the ocean floor.
6) With repeated eruptions over millions of years they can grow until they break the surface of the ocean and become volcanic islands e.g. Iceland.

What percent of Earth s total volume is the crust? Select one of the options below as your answer:a. 0.5%
b. 1%
c. 5%
d. 10%

Answers

The Earth's Crust contributes only about 1% to its volume - the correct answer is b). (it's no wonder since in some places it's only 3 miles thick!)

The biggest portion of the Earth's volume is taken up by the Mantle - around 84%. 15% of the Earth's volume are found in the innermost layer, the core.
