Seismic waves are sent through the earth during earthquakes, and those
energy waves are what cause the ground to shake as they travel through
it.Seismic waves travel at different speeds when they pass through
different types of material, so by studying seismograms, scientists can
learn a lot about Earth's internal structure.Body waves are seismic
waves that travel through Earth's interior, or its 'body.' Surface waves
are seismic waves that travel through Earth's surface.Surface waves are
important, but they don't provide much information about what happens
below the surface. For this, we need to study body waves so that we can
see what Earth's 'body' is like.
There are two types of body waves, called P waves and S waves. P
stands for primary waves because these waves travel the fastest and are
detected first. S stands for secondary waves because these are slower
than P waves, arriving second on the seismogram.

This is a short paraphrased summary of the article about ice cores in that website.
Answer: Researchers in labs may melt or crush bits of the ice core a little at a time, each deeper layer shows the time in the Earth's climate history. Tiny pieces of pollution, metals, radoiactive fallout, pebbles, sea salt, volcanic ash and even air bubbles all present important information that researchers can look for to track changes in the atmosphere's composition and temperature.

E Tropic of Capricorn or Southern tropic is one of the five major circles of latitude that mark maps of the Earth. It is the parallel of latitude at 23° 26′ 22″ south of the Equator, and is the farthest southern latitude that the sun can appear directly overhead, occurring on the December solstice. Its northern hemisphere equivalent is the Tropic of Cancer. Latitudes south of the Tropic of Capricorn are in the Southern Temperate Zone. North of this line are the Tropics.
<span>The Tropic of Capricorn is so named because about 2000 years ago the sun was entering the constellation Capricornus on the December solstice. In modern times the sun appears in the constellation Sagittarius during this time. The change is due to precession of the equinoxes. </span>
<span>The Tropic of Cancer (cancer is Latin for crab), or Northern tropic is one of the five major circles of latitude that mark maps of the Earth. It is the parallel of latitude that lies currently 23° 26′ 22″ north of the Equator. </span>
