Air pollution

This animation demonstrates the main sources of air pollution: agriculture, industry and urban settlements.

Oxygen cycle

The oxygen cycle describes the movement of oxygen within its three main reservoirs.

Ozone (O₃)

An allotrope of oxygen, consisting of 3 oxygen atoms.

Oxygen (O₂) (intermediate)

A colourless, odourless gas, an important component of the atmosphere, indispensable to sustain terrestrial life.

Carbon monoxide (CO) (beginner)

Colourless, odourless gas, highly toxic to humans and animals in high concentration.

Environmentally friendly vehicles

Combining a conventional internal combustion engine propulsion system with an electric propulsion system reduces emission.

Nitrogen (N₂) (basic)

A colourless, odourless, non-reactive gas, it constitutes 78.1% of Earth´s atmosphere.

Nitrogen monoxide (Nitric oxide) (NO)

A colourless, heavier-than-air gas, an intermediate in the production of nitric acid.

Oxygen (O₂) (beginner)

A colourless, odourless gas, an important component of the atmosphere, indispensable to sustain terrestrial life.

Sewage treatment plant

Treated sewage water can be used in agriculture and industry.

Soil pollution

This animation demonstrates the main sources of soil pollution.

Structure of the Earth (intermediate)

The Earth is composed of several spherical layers.

Sulphur dioxide (SO₂)

Sulphur dioxide emission is the main cause of acid rains. It is an intermediate product in the production of sulphuric acid.

Water pollution

The main sources of water pollution are industry, agriculture and urban areas.

How does it work - Refrigerator

This animation demonstrates how a refrigerator works.

Piesārņojums

Piesārņojums ir cilvēku darbības kaitīgā ietekme uz apkārtējo vidi.

Greenhouse effect

Human activity increases the greenhouse effect and leads to global warming.

Tardigrade

Tardigrades can survive in extreme environments, they can even stay alive in outer space.
