    1. Earth has a core of solid and liquid iron, a mantle of ultramafic rock, a crust of complex mineral compounds, and an atmosphere of nitrogen, oxygen, and other gases. Physical and chemical reactions on the Earth include the compound water (dihydrogen oxide or oxidane) in all three of its physical phases. Carbon-cycle (living) organisms utilize and alter the surface of the planet.

  59. Crust

    Earth's crust is made up of several elements: iron, 32 percent; oxygen, 30 percent; silicon, 15 percent; magnesium, 14 percent; sulfur, 3 percent; nickel, 2 percent; and trace amounts of calcium, aluminum and other elements.

    The crust is divided into huge plates that float on the mantle, the next layer. The plates are constantly in motion; they move at about the same rate as fingernails grow. Earthquakes occur when these plates grind against each other. Mountains form when the plates collide and deep trenches form when one plate slides under another plate. Plate tectonics is the theory explaining the motion of these plates.

    Mantle

    The mantle under the crust is about 1,800 miles deep (2,890 km). It is composed mostly of silicate rocks rich in magnesium and iron. Intense heat causes the rocks to rise. They then cool and sink back down to the core. This convection — like a lava lamp — is believed to be what causes the tectonic plates to move. When the mantle pushes through the crust, volcanoes erupt.

    Core

    At the center of the Earth is the core, which has two parts. The solid, inner core of iron has a radius of about 760 miles (about 1,220 km). It is surrounded by a liquid, outer core composed of a nickel-iron alloy. It is about 1,355 miles (2,180 km) thick. The inner core spins at a different speed than the rest of the planet. This is thought to cause Earth's magnetic field. When charged particles from the solar wind collide with air molecules above Earth's magnetic poles, it causes the air molecules to glow, causing the auroras — the northern and southern lights.Earth has multiple layers. The ocean basins and the continents compose the crust, the outermost layer. Earth's crust is between three and 46 miles (five and 75 km) deep. The thickest parts are under the continents and the thinnest parts are under the oceans.Earth is unique among the known planets: it has an abundance of water. Other worlds — including a few moons — have atmospheres, ice, and even oceans, but only Earth has the right combination to sustain life.

    Earth's oceans cover about 70 percent of the planet's surface with an average depth of 2.5 miles (4 kilometers). Fresh water exists in liquid form in lakes and rivers and as water vapor in the atmosphere, which causes much of Earth's weather

  63. We live on the outermost layer of Earth, called the crust. This varies in depth between 5 and 75 km. It’s mostly made of silicates, with a tremendous amount of oxygen mixed in. In fact, 47% of the Earth’s crust is oxygen. The thickest parts of the crust are under the continents, and the thinnest parts are underneath the oceans.

  126. This question has both a simple and a complicated answer. There are three basic types of rocks: igneous, sedimentary, and metamorphic. Within each of these groups, however, there are hundreds of subdivisions based on the types and amounts of minerals the rock contains and/or the rock's texture.
    These three basic rock classes are defined by how the rock formed.

    Igneous rocks such as granite and basalt form when molten rock cools inside the earth or during volcanic eruptions, respectively. Sedimentary rocks are the product of physical and chemical processes at the earth's surface that cause the breakdown of other rocks into small pieces known as sediments. The small pieces of rock then get "glued" together to form "clastic" sedimentary rocks, such as sandstone and shale. Limestone and gypsum are two examples of "chemical" sedimentary rocks that form as a result of chemical reactions in water.

    Metamorphic rocks are igneous or sedimentary rocks that have been changed because of exposure to high temperatures and/or pressures. When rocks are heated or squeezed, the original minerals in the rock may change into other minerals or reorient themselves, altering the rock's chemical composition and texture. Common examples are marble (metamorphosed limestone) and slate (metamorphosed shale).

    Most of the rocks we see on the earth's surface are sedimentary. Igneous rocks are most common inside the earth. Metamorphic rocks are found in mountains and other places where forces due to movements of the earth's plates cause rocks to deform, as well as inside the earth, where rocks are subjected to pressure from the overlying rocks and heat from both radioactive decay and the earth's core.

  139. The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Earth's surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases.
