A:The crust, the outermost layer or surface layer, is the thinnest layer of Earth. In addition to being thin, the crust layer has the most variance when it comes to thickness. This diverse layer mostly ranges from 5km to 30km in thickness but can reach depths of 70km.
A:The outer core, one of the three layers of the Earth, is approximately 1,430 miles (2,300 kilometers) thick and between 7,200 and 9,000 F. According to National Geographic, the outer core is mostly composed of iron and nickel in a liquid alloy form.
A:According to Universe Today, the temperature of the Earth's crust is the same as the outside temperature at any given location.For example, the crust in the region of Antarctica is cooler than the crust in warmer regions of the world, like South Africa.
A:Magnetism is a phenomenon of physical science that arises due to the forces between objects brought about by the motion of electrical charges within those objects. The motion of electric charges creates a magnetic field, which exerts a magnetic force on charged particles that move within that field. A magnetic field flows from one end of an object to the other, creating a dipole with positive and negative ends.
A:Molten rock is rock heated to a temperature that is sufficient to turn it into a thick liquid. Molten rock often is associated with lava from a volcano. Additionally, molten rock exists below the surface of the Earth.
A:Earth's solid mass is composed of iron, oxygen, silicon, magnesium, sulfur, nickel, calcium and aluminum. These materials, according to Learner.org, are spread unequally among the planet's three main shells: its core, its mantle and its crust (from deepest to outermost).
A:As of April 2013, scientists have recorded the temperature in the center of the Earth to be 6,000 degrees Celsius. This is 1,000 degrees hotter than the measurement previously recorded from an experiment run 20 years prior.
A:Dr. Inge Lehmann discovered the makeup of the Earth's inner core by studying how an earthquake's waves bounced off the core. It was previously thought that the core was made of liquid, surrounded by solid mantle and a crust. Lehmann found that the Earth's center is made of a solid inner core surrounded by a liquid outer core.
A:The three layers of the earth, in order from outside to inside, are the crust, the mantle and the core. The mantle is the thickest and most massive layer, while the core has the highest temperatures of anywhere in the planet.
A:The Earth has two solid parts: the outer crust that covers the surface, and the inner core, which is primarily made of iron. Earth has three layers that make up nearly 4,000 miles of rock, solid metals and liquid metals.
A:The Earth is divided into four layers: crust, mantle, outer core and inner core. The crust is the only layer of Earth that hosts life, as the mantle, inner core and outer core are too hostile for organisms to exist.
A:The state of the mantle, the layer of Earth between the crust and the core, depends on its depth. Near the surface, the rock is very hard and dense. Deeper in, immense heat and pressure render the rock into a semisolid, or plastic, state.
A:Continental and oceanic crust are both destroyed in subduction zones and lie atop Earth's mantle, though they differ in thickness, density, age and chemical composition. A subduction zone is an area of Earth's crust where tectonic plates meet.
A:A break in the Earth's crust is called a fault. According to Dictionary.com, a fault in geology is a fracture in the Earth's crust that results in the displacement and loss of continuity of rocks on either side of the fracture plane. A fault is the result of plate-tectonic forces.
A:The temperature of the continental crust varies depending on location and depth; at the surface, the continental crust exists at the same temperature as the outside air, while its inner core reaches temperatures up to 1600 degrees Fahrenheit. The continental crust consists of many levels, and exists on land and underneath the ocean. The top layer of the crust below the ocean floor typically experiences cooler temperatures than the crust forming the ground on land masses, but both have hot inner cores.
A:The Earth's crust is solid matter. Both oceanic and continental crusts are made entirely of rock. The former is primarily composed of denser material such as basalt, and it is, on average, 4 miles thick.
