what are the chemical properties of the earth?
90193
The composition of the atmosphere of Earth is 21 percent molecular oxygen, 78 percent molecular nitrogen, and 1 percent argon. Trace amounts of carbon dioxide, water vapor, and other gases are also present.

1.4 Physical and Chemical Properties. The physical properties of minerals include name, crystal system, color as it appears to the naked eye, streak by rubbing on streak plate, luster, hardness on the Mohs scale, and average specific gravity.

The terrestrial inner planets are composed largely of refractory minerals, such as the silicates, which form their crusts and mantles, and metals such as iron and nickel which form their cores. Three of the four inner planets (Venus, Earth and Mars) have atmospheres substantial enough to generate weather.

Atmosphere, composition and structure. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and 0.93% argon. The remainder, less than 0.1%, contains such trace gases as water vapor, carbon dioxide, and ozone. All of these trace gases have important effects on Earth's climate.

Alkaline Earth Metal Properties Atoms have a low electron affinity and low electronegativity. All of the alkaline earths are shiny, silver-colored metals at ordinary temperatures and pressure. These metals are malleable and ductile.

Like the other terrestrial planets, Earth has a rocky surface with mountains and canyons, and a heavy-metal core. Earth's atmosphere contains water vapor, which helps to moderate daily temperatures.
1436332
Soil properties. All soils contain mineral particles, organic matter, water and air. The combinations of these determine the soil's properties – its texture, structure, porosity, chemistry and colour. Soil is made up of different-sized particles.

Chemical Properties. ... Some common physical properties are odor, density, melting point and boiling point, while some common chemical properties are heat of combustion, enthalpy of formation, toxicity, and flammability, each of which will be covered in this lesson.

Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays.

The Earth consists of three layers: the crust, the mantle and the core. The core, the innermost layer, is rich in iron and very dense. It can be further subdivided into the inner and outer core. The mantle is the intermediate layer of the Earth and can be subdivided into the inner and outer mantle.
388989
The layers of Earth are: Crust - 5 to 70 km thick. Mantle - 2,900 km thick. Outer Core - 2,200 km thick.
509875
The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.
