How We Learned That Water Isn't An Element
To learn more about this topic, start your googling with these keywords: Chemical element: is a species of atoms that have a given number of protons in their nuclei. Chemical elements cannot be broken down into simpler substances by any chemical reaction. Atom: is the smallest unit of ordinary matter that forms a chemical element. Molecule: is a group of two or more atoms held together by attractive forces known as chemical bonds. Inflammable air: an old name for hydrogen. Hydrogen: is the most abundant chemical substance in the universe. Early chemists identified hydrogen gas because it was colorless, odorless and highly combustible. Hydrogen means "maker of water" in Greek. Dephlogisticated air: an old name for oxygen. Oxygen: is Earth's most abundant element. Early chemists identified oxygen gas because it was colorless, odorless and was essential for respiration and combustion. Diatomic molecules: are molecules composed of only two atoms, of the same or different chemical elements. At standard conditions, both hydrogen and oxygen are gasses of diatomic molecules (H2 and O2, respectively). Water: is an inorganic, transparent, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms. Combustion (or burning): is a chemical reaction between a fuel and an oxidizing agent (like oxygen gas), that produces oxidized, often gaseous products, in a mixture termed as smoke. Electrolysis: is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Avogadro's Law (sometimes referred to as Avogadro's hypothesis): is an experimental gas law that states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.

Why Continents Are High
To learn more about this topic, start your googling with these keywords: Tectonic plate: Earth’s rigid outer layer is broken up into a bunch of pieces, called tectonic plates. Usually people think of tectonic plates as the Earth’s crust, but the plates are actually made of the crust PLUS the very top of the mantle, which is cool enough to be rigid and hard and stuck to the crust. The crust and the top of the mantle together are called the “lithosphere.” Underneath that is a part of the mantle called the “asthenosphere,” which is the part that oozes and flows. Subduction Zone: The area where two tectonic plates collide and the denser of the two is forced under and dives down into Earth’s mantle. Mariana Trench: The subduction zone where the Pacific Plate slides under the Philippine Plate. The edge of the Philippine plate is kind of pulled down in the process, creating a deep crevice in Earth’s surface, known as a deep ocean trench. The Mariana Trench is the deepest ocean trench in the world. Granite: A type of igneous rock formed when magma cools slowly underground (creating relatively large crystals). Granite is different from other igneous rocks like basalt because it has a higher percentage of low-density minerals like quartz and feldspar. Oceanic-Continental Convergent Plate Boundary: The boundary between a tectonic plate made of oceanic lithosphere and a tectonic plate made of continental lithosphere. At these “convergent” plate boundaries, the two plates are colliding, and the oceanic plate is forced to subduct, or sink, under the continental plate. Ring of Fire: A long stretch around the Pacific Ocean where plates are colliding. The majority of volcanoes and earthquakes in the world take place along the Ring of Fire. Silicate minerals: These are the low-density minerals like quartz and feldspar. They contain SiO2. Because silicate minerals are thick/viscous when melted, magma with lots of silica in it forms very explosive volcanoes, like Mt. St. Helens and Mt. Tambora.
