Does a jellyfish poop?
They throop through their manus.
That’s because jellyfish doesn’t technically have mouths or anuses, they just have one hole for both in things and out things, and for biologists, that’s kind of a big deal.
Does sand contain oxygen?
Silica, SiO2, is composed of Silicone and Oxygen. It has been known since ancient times, is found in sand, and is a major component of glass. Silica is a chemical compound, also called silicon dioxide.
What is sand made of chemically?
The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz.
How deep is the sand at the beach?
The shoreline moves back and forth and beaches can stack to thicknesses of many 100’s of meters. I’ve drilled beach sands of over 700m thickness. Excluding stacking, beach sand thicknesses seem to average between 1 and 3 meters.
How do mermaids poop?
They poo out of a hole, called an ‘anus’, in their bottoms; and wee using a different hole. … Well, since a mermaid has a human top half and a fishy bottom half, I think she would poo through a vent on her tail.
Is glass made out of sand?
Glass is a form of liquid sand. Different types of glass will slightly differ in their make up, but generally speaking, glass is a mixture of sand, other recycled glass, calcium carbonate, sodium carbonate, and a whole lot of heat. Sand melts at the extremely high temperature of 3090 degrees F.
Why is it called sand?
The word sand is thought to have originated from an Old English word, which itself originated from the old Dutch word sant, which became zand (meaning, you guessed it, sand). … The word then came to mean something that was finer than gravel, but coarser than dust.
How deep is sand in the Sahara?
141 ftThe depth of sand in ergs varies widely around the world, ranging from only a few centimeters deep in the Selima Sand Sheet of Southern Egypt, to approximately 1 m (3.3 ft) in the Simpson Desert, and 21–43 m (69–141 ft) in the Sahara.
How old is the sand on the beach?
As a final sandy thought, consider the fact that the sand on most of our beaches, especially on the East and Gulf Coasts, is rather old: some 5,000 years or so, Williams said.
How much of sand is fish poop?
Two researchers working in the Maldives found that the 28-inch steephead parrotfish can produce a whopping 900 pounds of sand per year!!! When you consider these larger amounts, it is easy to understand how scientists estimate that more than 80% of the sand around tropical coral reefs is parrotfish poop!
Where does a fish poop from?
A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills.
Is sand a poop?
The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.
Is there sand at the bottom of the ocean?
there is NO SAND in the bottom of the ocean. Sand, crushed up rock, ground up silica is made be grinding rocks together. Think glaciers 1+miles deep pressing down on giant landforms and moving along the surface at 1 mile every 10 years for 3 million or more years; that is a sand machine.
What is under the sand on a beach?
Originally Answered: Whats under the sand at a beach? Sand is basically just finely ground up rock material – and under the sand, you will find the rocks of the shore. … If you move back from the shore until you are off the beach, you will likely find the same bedrock which underlies the sands.
What is sand made of?
Sand is typically made mostly of varying amounts of material weathered from inland rocks (or seacliff material) and transported to the beach on the wind or in rivers, and/or shells and other hard parts precipitated out of the ocean water by marine organisms. Sand therefore records processes at a variety of timescales.
