All the following products made from petroleum expect GASOLINE.
Answer:
Continental drift in terms of plate tectonics.
Explanation:
- Continental drift is a theory given to explain the formation of various plates or slabs on the surface of the earth and the theory is evident in the form of Alfred Wegener as a geologist who through his research and discoveries and advanced knowledge gave the concept.
- Plates on which the landmasses and various features are made is not static as it looks and is more dynamic and was more destructive in the past as the formation of the earth during the 4.6 billion years ago the continental landmass underwent transformations and breakthrough happened as the split and rejoined and again joined to form what is seen today.
- These plates drifted in such ways that the landmasses formed various properties of the northern and southern hemispheres. Wegener gave evidence of Jigsaw fit puzzle, drifting of the climatic zones, spreading of the plants and animals located at the same continental borders.
- Moving of the plates under the action of gravity and wind speeds.
The core has the largest density, being made of iron and nickel
The mantle has an intermediate density and the crust has the lowest density.
Answer:
plate boundaries
Explanation:
Volcanoes and earthquakes are most likely to form along plate boundaries.
Earthquakes:
An earthquake is generated when two plates move relative to each other. The earthquake itself, is the movement felt on the surface caused by the movement of the tectonic plates at their boundaries. There are a few different types of plate boundaries, NOAA does a great job giving a brief description of each here:

Answer:
The most vital function of Earth's magnetic field is to deflect most of the solar winds. The solar winds are dangerous level of radiation, that would kills us without our magnetic field.
