Eruption with low silica tends to be nonexplosive. The type of lava is Basaltic, flows easily because of low viscosity (low gas content- originates in the mantle). This type of lava comes from shield volcanoes (low angle slopes and gentle)- eg. Manua Loa Volcano and Hawaii.
<span><span>Earth's atmosphere traps energy from the sun, whichcauses meteors to burn up.
allows ozone to form easily.
allows solar radiation to penetrate to the surface.
allows water to exist as a liquid.
Air has pressure because
wind moves the air.
the stratosphere is thick.
temperature warms the air.
air has mass.
The layer of the atmosphere between the stratosphere and the thermosphere is called the
mesosphere.
troposphere. (below stratosphere)
exosphere.
ionosphere.
When climbing a high mountain, you get out of breath easily because
air pressure is greater.
