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...
What is the densest metal? What is atomic weight measured in? What element is the most abundant in the Earth's crust by weight? What do you call a substance containing only one type of atom? Which atom has the smallest number of neutrons?
Discuss with the whole class what the relative thicknesses of the layers are — that the inner core and outer core together form the thickest layer of the Earth and that the crust is by far the thinnest layer. What is the hottest layer of the Earth? The core is the hottest, densest pa...
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. ...
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...
What is the densest chemical element? What is the main element in emeralds and aquamarines? How are non-silicate minerals classified? What metals are found uncombined in the Earth's crust? What is the definition of hardness in chemistry? What are precious metal compounds?Explore...
which ended about 3.8 billion years ago, wasn't responsible for all of the craters on the moon. large and small asteroids continued to pelt the surface, but at a slower pace, leading to overlapping craters and craters on top of lava flows. the crust of the moon is made up of a rocky...
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 the most abundant gas in Earth's atmosphere? Composition of Earth's Atmosphere The atmosphere is made of gas and lots of it! Although the atmosphere contains many types of gas, one gas accounts for more than 70% of Earth's atmosphere, making it by far the most abundant. ...
