What is another name for the transition metals? What properties do all compounds have? What minerals are mined for titanium? Which of the first 20 elements in the periodic table are metal and which are non-metals? What metals are found uncombined in the Earth's crust?
What is the lightest alkaline earth metal? What metal is the best electric conductor? What is the most reactive metallic atom? What is the most abundant metal element in the Earth's crust? What alloy is used to hold molten metals?
The troposphere, the bottommost layer of Earth’s atmosphere, is the densest of the five atmospheric layers and extends from ground level up to about 10 kilometers in altitude. This is the layer where humans live and breathe, as it contains the air we depend on for survival. The tropospher...
All it needs is some good marketing. One selling point might be that most if not all mined iridium ultimately comes from meteorites, which contain 300-1500 times as much iridium as the earth’s native crust. OK, that’s iridium. Now here’s the weird deal on osmium. A series of web...
Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, ishotter and denser because temperature and pressure inside the Earth increase with depth. ...
The crust of Mercury is likely very thin, thinner than Earth's. The outer shell is only about 300 to 400 miles (500 to 600 km) thick. The planet has no plate tectonics, which is part of the reason the cratered surface has been preserved for billions of years. The core of the mat...
The crust is the outermost layer of the planet, the cooled and hardened part of the Earth that ranges in depth from approximately 5-70 km (~3-44 miles). This layer makes up only 1% of the entire volume of the Earth, though it makes up the entire surface (the continents and the ocea...
What is a Mineral? 1. Occurs naturally 2. Solid 3. Has a defined chemical composition 4. Atoms arranged in an orderly pattern 5. Was never alive- Inorganic Mineral Identification Approximately 4,000 known minerals About 30 are common These are the rock forming minerals (because they are the...

Like the other planets of the inner Solar System,Earthis also a terrestrial planet, composed of metals and silicate rocks differentiated between an iron core and a silicate mantle and crust. Of the terrestrial planets, it is the largest and densest, with an average radius of 6,371.0 km (3...
