What is bad about iron ore?

However, mining of iron ore has copious negative impacts on the environment. It degrades natural landscapes, surface and ground water quality, flora and fauna, as well as the ambient air quality within the mining area and its environs.

What causes Earth’s magnetosphere?

The magnetosphere is formed by the interaction of the solar wind with Earth’s magnetic field. The pressure of the solar wind on Earth’s magnetic field compresses the field on the dayside of Earth and stretches the field into a long tail on the nightside.

What affects the Earth’s magnetic field?

The Earth’s magnetic field is mostly caused by electric currents in the liquid outer core. The Earth’s core is hotter than 1043 K, the Curie point temperature above which the orientations of spins within iron become randomized.

How does iron ore affect the economy?

Each iron ore mining job, which includes good pay, health and retirement benefits, generates an additional 1.8 jobs in other industries. Mining operations purchase goods and services from other industries, including utilities, transportation and manufacturing.

How does mining ore affect the environment?

Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to create space for the storage of the created debris and soil.

How does magnetosphere affect solar wind?

The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind – the constant flow of charged particles streaming off the sun. Constant bombardment by the solar wind compresses the sun-facing side of our magnetic field.

Is the magnetosphere weakening?

In the past 200 years, Earth’s magnetic field has weakened about nine percent on a global average. Some people cite this as “evidence” a pole reversal is imminent, but scientists have no reason to believe so.

Why is the magnetosphere important?

Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun. It also provides the basis for navigation with a compass.

How does iron ore mining affect the environment?

The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.
