What is the name of the part of the eye that holds the iris? How are the eyes positioned in the frog's head in comparison to the positioning of persons eyes? Human eyes are positioned on the sides of the nose, 1/3 of the way down the face. The frogs are positioned on the top 1/3 - enabling them to look out of the water without comiâ¦ng all the way out.
The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas particles that are colliding.he lights are known as 'Aurora borealis' in the north and 'Aurora australis' in the south. Scientists have learned that in most instances northern and southern auroras are mirror-like images that occur at the same time, with similar shapes and colors.
They accelerate along the Earth's magnetic field lines which concentrate at the poles. The particles then plunge into the upper atmosphere (3) where they collide with the gases that surround the Earth. These collisions create energy, and the excess energy is given off in the form of light emissions. We call these light emissions the Northern Lights.
