Answer:
The correct answer is Layer B!
Explanation:
The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core
Answer:
C. Earth's solid surface layer sits on a moving, semiliquid layer.
Explanation:
Earth is highly tectonically active because the solid layer of the earth sits on a moving, semi-liquid layer.
The earth's crust is broken into slabs. Together with part of the upper mantle, they form a layer called the lithosphere. These solid lithospheric bodies are called tectonic plates.
- Under the plates is a semi-molten layer under great temperature.
- As the molten layer moves, it carries the lithosphere on top of it.
- This causes the movement of the plates in different directions.
- The semi-liquid layer is called the asthenosphere
This is the reason why the earth is tectonically active.
Answer:
Education
Explanation:
Welfare and education are the largest expenditures by state governments. The expense on education is shared by states and counties, with the counties spending the majority of their funds on county public schools, and the states sharing the burden of financing post-secondary state education.
One of the most important roles of the rainforest is moderate destructive drought and rain cycles in local areas.
The answer is "5 minutes and 35 seconds".
Earthquakes create three kinds of seismic waves which are:P-waves that are primary waves, S-waves that are secondary wavesand surface waves,which land at seismic account stations in a steady progression.Both P and S waves enter the inside of the Earth while surface waves don't. Because of this, P and S waves are known as "body waves"
