Organic matter is the remains of dead plants and animals, in the process of decomposition, as well as their waste (excrement and urine). Organic matter forms humus, or black earth, which is fine as flour. This material is rich in minerals and very useful for feeding plants.

What is in the center of the Earth?

The inner core of our planet, made of solid iron and surrounded by a thick layer of rotating liquid iron (the outer core), can only be studied through seismic waves generated by underground earthquakes and tremors.

What is below the Solar System?

– 5 dwarf planets identified (Ceres , Pluto , Haumea , Makemake , Eris ), although there could be dozens or hundreds. – 472 satellites orbiting planets and dwarf planets identified.

That’s fine and still valid. A few years ago we could respond in this way: “gravity does not exist in outer space and, therefore, there is neither up nor down, neither right nor left, neither north nor south” because “the force of gravity is linked to stars physical like planets and stars.

What are the names of the layers of the earth?

The three main layers that make up the internal structure of the Earth are the Crust, the Mantle and the Core (see image).

What is the most important layer of soil?

The deepest layer or C horizon, formed by the original bedrock, is what gives the soil its mineral characteristics. The A horizon, the most superficial and where the vegetation takes root, is rich in organic matter.

What is the depth of the earth?

The central point of the Earth is more than 6,000 km deep. But even the outermost part of the core is about 3,000 km below our feet. The deepest hole ever drilled on the surface is the Kola Super Deep Well in Russia and it is only 12.3 km deep.

What are the worms that live underground called?

Nematodes have populated almost every corner of the world.

They live in Antarctica, in the entrails of other animals -including humans- and even inside sperm whale placentas. Definitely, if there is an animal that could live inside the Earth, it would be this worm.
