Realists are usually interested in 'things' - such as buildings, mechanics, equipment, tools, electronics etc. Their primary focus is dealing with these - as in building, fixing, operating or designing them. Involvement in these areas leads to high manual skills, or a fine aptitude for practical design - as found in the various forms of engineering.

Realists like to find practical solutions to problems using tools, technology and skilled work. Realists usually prefer to be active in their work environment, often do most of their work alone, and enjoy taking decisive action with a minimum amount of discussion and paperwork.

Earth Science

Earth Science

Are you curious about how the physical world works? Earth Science deals with the physical features of the planet itself. This includes Geologists, who study the ground under our feet, what it’s made of, how it was created and how it’s changing. Geologists search for fuels and minerals, study natural hazards, and work to protect Earth's environment. Meteorologists and climatologists study the atmosphere and oceanographers the oceans; their composition, movement, organisms and processes. 

Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment and design methods to protect the planet. Some use their knowledge about Earth processes such as volcanoes, earthquakes and hurricanes to plan communities that will not expose people to these dangerous events.

Earth Scientists play a central role in the race to understand how dynamic earth systems are changing and what we might be able to do about such change.

Some examples of the work that scientists are engaged with in this sector include; developing natural resources such as wind, wave and solar energy in ways that safeguard the environment, predicting the behaviour of Earth systems and the universe, finding adequate supplies of natural resources, such as ground water, petroleum, and metals, conserving soils, maintaining agricultural productivity and maintaining quality of water supplies.

Many earth scientists will work in public service roles, engaging in science communication or working to understand the risks from natural phenomena such as volcanos, tsunamis and earthquakes.

Occupations in Earth Science
(sorted by Job Zone)

Meteorological Officer

A technical grade in Met Eireann with responsibility for the preparation and dissemination of weather data and related tasks.

Soil Scientist

Soil scientists study soil and advise clients on its management and conservation. They survey and map soils, and produce information on their various properties and possible uses.

Geoscientists are primarily involved with the exploration and production of natural resources. Their research requires detailed research into the composition, structure and other physical aspects of the earth.
Solar Physicist

Carries out research towards a better understanding of how solar activity affects the earth and the atmosphere.

Meteorologist / Weather Forecaster

Studies the weather and weather systems to forecast future weather conditions.

Landscape Scientist

Uses scientific knowledge of the environment to solve and prevent practical landscape problems.

Studies the rocks, minerals and fossils that make up the crust of the earth.
Geological Technician

Geological technicians help and support the work of geoscientists including geologists, geochemists and geophysicists whose work involves the study of the Earth's rocks and minerals.


Works in exploration or research in an area such as biology, chemistry, or physics, that deals with the objects, phenomena, or laws of nature and the physical world.

Research Scientist

Plans and carries out experiments and investigations to increase scientific knowledge in a range of areas such as life sciences, including physiology, pharmacology, microbiology, plant sciences.

Mathematical Modeller

Uses mathematical models and applications to illustrate processes or solve complex problems.
