Solar System Myth Busting
How much about our
Solar System do you think you know?
It has never ceased to amaze me how little people know about
their own planet. But to be fair, it is
a huge planet…it is 24,901 miles around, and weighs in at 5.972 x 1024
or 5,972,000,000,000,000,000,000,000 Kg.
(1.31664252 × 1025 lbs).
That is a lot of Earth to learn about.
But today we are going to leave the comfort of our small Planet and
venture out into the solar system. But
don’t worry, we won’t go too far in our myth busting adventures. Today we will focus on tackling just 4 myths. So without further delay, put on your space
suits and let’s go!

Breaking Down the Myths on Weathering and Erosion
Breaking
Down the Facts and Myths on Weathering and Erosion
When I
talk to people about Weathering and Erosion I can hear some crazy things. Some people insist that because they can’t
see it, it doesn’t happen. Others will
act as if this is an overnight process, which is also wrong. The answer lies somewhere in between the
two. So let’s start breaking the
barriers and getting this straight.

It’s Time to Get Shakin’
It’s Time to Get Shakin’
Today on Earth Science for
Everyone we are going to demystify another set of bad science facts. From the
title of this post you can probably guess what the subject matter is about, but
for those who didn’t make that connection, its Earthquakes! Now depending on how much you paid attention
in Science class and how many movies you watched, I can guarantee that at least
one of these items will be news to you!

Versus: Pumice & Scoria
| Choice: A |
 |
| Choice B |
VS
Today on Versus we have Pumice and Scoria...Both of these rocks are considered Vesicular, (meaning they are filled with TONS of tiny holes and tubes) and both are associated with Volcanoes. So how do we tell them apart? Well first let me tell you that the Pumice (yes the same kind you scrub on your feet to make them smooth) is indeed Choice A.
Pumice:
Is considered a Felsic rock, meaning that it has a lot of Quartz in it (think sand). Pumice forms almost like a glass filled with bubbles due to a rapid cooling of rocks ejected from the volcano. The best way to separate the Pumice from the Scoria is to see if it floats in water.
Scoria:
It is considered a Basaltic rock, meaning that is formed from very little Quartz (remember sand). Scoria forms from the rapid cooling of molten rocks and the best way to tell it apart from Pumice is that it sinks!
