Earth's Second Atmosphere The second atmosphere, which was the first to stay with the planet, formed from volcanic outgassing and comet ices. This atmosphere had lots of water vapor, carbon dioxide, nitrogen, and methane but almost no oxygen.
<span>Stage 4 demographic means that the population is stabilized by a low rate of births and deaths. Out of the 4 options it would be most likely that western Europe's population would stabilize this way since it is one of the oldest and advanced, so rapid growth would be low and death rates reduced by advances in medicine.</span>
Convection in the mantle and pressure of magma on the edge of the plate
Explanation:
Convection currents occur in the mantle because the upper mantle (asthenosphere) is generally cooler than the lower mantle. The convections apply upward pressure on the lower edges on the lithosphere as the melted rocks upwell from below. The lithosphere deflects the convections and as the convections churn clockwise of anticlockwise, they drag the lithosphere with it via friction. This is what is stipulated to cause tectonic plate movements.
