The chemical and mechanical characteristics of the earth allow to find the correct answers for the questions are:
1. Student A described the continental type and Student B described the oceanic type.
2. The nucleous have temperature is : high and the presure is: high
3. Convection currents in the Mantle.
Planet Earth has an internal structure that determines mechanics and chemistry properties. The parts are:
- Atmosphere. Gaseous part that envelops the planet
- Cortex. Most superficial solid part of the plant in it is all life
- Mantle. Section of plastic properties of fluid type material
- Nucleus. Inner section where the terrestrial magnetism originates.
The crust is formed by the continental plate of between 5 to 20 km and the oceanic plate that is thinner, everything is formed by basalt and silicates.
The mantle extends up to about 2900 km, in general the mantle is solid, but the pressures and high temperatures make the material behave like a fluid that can be moved by convection currents.
The core is the innermost part of the earth, despite the high temperature the enormous pressure creates that it solidifies as we descend, in this is almost all the iron on the planet and its movement creates the earth's magnetic field.
Let's review the statements for each question:
Question: 1) What type of outer layer do they describe?
a) False. The oceanic layer is thin.
b) False. The continental layer is thicker.
c) Flase. The oceanic layer is thin and the continental layer is thick.
d) True. Student A describes the continental part and student B the oceanic part.
Question: 2) How is the temperature and pressure in the core
a) False. The pressure is high due to the amount of matter above.
b) False. The temperature is high due to compaction of the material.
c) False. It is contrary to all experimental data.
d) True. The temperature and pressure are high due to the amount of matter above the nucleus.
Question: 3) Explain how these convection currents move and what layer(s).
The Convection currents are quantities of matter in a fluid state that move slowly energy carrier, in general they occur in it from the innermost part of the mantle to its outermost part of the mantle that has less temperature.
Therefore the convection currents in the Mantle.
In conclusion with the chemical and mechanical characteristics of the earth we can find the correct answers for the questions are:
1. Student A described the continental type and Student B described the oceanic type.
2. The nucleous have temperature is : high and the presure is: high
3. Convection currents in the Mantle.
