What is earth science?
Earth science is a multidisciplinary field that integrates key elements of geology, geography, and environmental science to tackle modern problems across our rapidly changing planet. Earth science can include the study of the Earth’s surface and any matter on, above or below it; the atmosphere around us; our oceans; all the way up to the space beyond our planet (planetary and cosmochemistry).
Earth science delves deep into the past and considers consequences far into the future.
It tracks 4.6 billion years of geological history, considering the ways in which the Earth (and the Solar System) has evolved from a mass of molten rock to moving continents, changing oceans and teeming life forms.
Earth science is categorised into different branches, with a variety of specialisations and careers available in fields such as geology, geography, , environmental science, palaeontology, planetary science, cosmochemistry, natural hazards, , meteorology, and hydrology.
Aspects of geology, including minerals, rocks, and landforms are studied alongside plate tectonics and Earth history to understand formation of mineral deposits and natural hazards. Today, more than ever, exploration, discovery and mining of strategic critical new minerals and metals (lithium, tantalum, tungsten, copper and cobalt) and other resources (hydrogen, helium, etc), are needed to help address a whole range of emerging technological and environmental issues facing society as we transition away from carbon energy towards green energy alternatives.
investigates how soils sustain life on earth, and how soil properties and processes influence plant growth, water cycling and quality, as well as gaseous exchanges with the atmosphere.
focuses on the exchange of elements between the different “-spheres” or “-omes” on Earth and other planets, which may include the release of nutrients to the ocean from weathering of rocks to the damaging impacts of heavy metals and environmental contamination.
is concerned with water resources management. Common issues in countries around the world include water quality, water pollution and treatment, salinity, irrigation hydrology, seawater intrusion, the role of water in climate change and global hydrology.
Meteorology, known by most as a study of the weather, looks at the atmosphere and air around us more broadly. Beyond forecasting rain or sun for the nightly news, the science of meteorology—coupled with geology and —explores long-term climactic trends that are integral to our understanding of climate change – past, present and future.
What does an earth scientist do?
Earth science forms the foundation of many scientific investigations and has broad applications.
When you work in Earth science, you may be part of a geological or environmental team investigating aspects of or natural hazards. You may also work with ground water, surface water, landform development, soil fertility, sustainability of Earth’s resources, responsible exploration and mining of minerals, water, pollution monitoring, and on indigenous issues relating to the environment.
As an earth scientist, you will have the formal qualifications and knowledge needed to tackle a range of issues and careers related to adaption and resilience. You will understand the theory of , spanning from early geological times to the present. You will also develop the scientific and analytical expertise to apply your knowledge to new and innovative solutions, driving an evidence-based approach to change in our current world.
Working in the Earth Sciences, you will have the opportunity to travel to diverse field locations and spend time onsite on mines, in rural or urban settings, and in the wilderness and national parks, even out on the open ocean, collecting samples and conducting assessments. You may also work back at the laboratory, analysing and writing reports to translate your findings into practical action plans.
Working in earth science in Australia, another avenue you may pursue is to specialise in and habitat protection and conservation. Here you would consider the Australian soil mantle and human interactions with these elements of the natural environment. Resource companies are among the businesses that regularly engage the expertise of to undertake classification and mapping, as well as analysing soil components, organisms and ecology.
Coastal management is yet another field that may leverage the specialist expertise of earth science. You could work on maritime projects, such as managing dredging campaigns or the construction of shipping channels and other navigational infrastructure, or with local councils and state governments on beach nourishment and coastline development.
You may also put your skills to work to design hydrology solutions for dams, reservoirs, rivers and lakes, in a range of urban or rural settings, both inland and coastal.
Increasingly, technology will also be part of your day-to-day working life in earth science, as you use software to model a range of scenarios and manage complex data requirements.
