The thick parts of the Earth's crust that form large land masses are called continents. Continents are made up of a variety of rocks and have different geological features such as mountains, plains, and plateaus. There are currently seven continents on Earth.
they are crust and the mantle and also the core
about 0.003 parts per billion in the earth's crust.
earthquakes happen when sections of the earths crust shift.These shifting parts called plates,are actually pieces of the crust floating on the hot molten interior of the earth. The majority of earthquakes happen along the edges of those plates,and along weak areas of the crust called fault zones
The oldest parts of Earth's crust are found on continents because continental crust is less dense and typically more buoyant than oceanic crust, allowing it to survive longer without being subducted back into the mantle. In addition, continental crust is continuously being built up through processes like volcanic activity and mountain building, preserving older rocks and structures.
The youngest crust is nearest the mid-oceanic ridges, where new crust is formed from upwelling magma.
Tectonic Plates
The three parts that make up the Earths mantle are the crust, core, and mantle.
The three parts that make up the Earths mantle are the crust, core, and mantle.
The parts of the Lithosphere are the crust, mantel and core.
majority of valcanoes follow the edges of the tectonic plates, which are the weaker parts of earths crust, therefore volcanoes form durin the crust giving away to the pressure built up. other volcaoes form other places due to weak parts of earths crust
they are crust and the mantle and also the core
There three basic part of earth are The crust The mantle The core
yes
The three parts that make up the Earths mantle are the crust, core, and mantle.
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
Neodymium is relatively abundant in the Earth's crust, with an average concentration of about 38 parts per million. It is considered a relatively common rare-earth element compared to others in the lanthanide series.
about 0.003 parts per billion in the earth's crust.
