On Earth, soil is generally considered to be weathered material capable of supporting plant life.[2] Soil forms through a variety of soil formation processes, and includes weathered rock "parent material" combined with dead and living organic matter and air. Soils are vital to all life on Earth because they support the growth of plants, which supply food and oxygen and absorb carbon dioxide and nitrogen.\n\nIntroduction\nBecause of it's position in the landscape and its dynamic physical, chemical, and biologic functions, soil is among our most important natural resources. Indeed, engineers, agronomists, chemists, geologists, geographers, biologists, microbiologists, sylviculturists, sanitarians, archaeologists, and specialists in regional planning, all depend on, and contribute to, knowledge of soils. While the general concept of soil is well established, the definition of soil varies, hinging on the perspective of the discipline or occupation employing it as a resource.\n\nSoil occupies the pedosphere, one of Earth's spheres that the geosciences use to conceptually organise the Earth. This is the conceptual perspective of pedology and edaphology, the two main branches of soil science. Both branches apply a combination of soil physics, soil chemistry, and soil biology. Due to the numerous interactions between the biosphere, atmosphere, and hydrosphere that are hosted within the pedosphere, more integrated, less soil-centric concepts are also valuable. Many concepts essential to understanding soil come from individuals not identifiable strictly as soil scientists. This highlights the interdisciplinary nature of soil concepts.\n\nThe understanding of soil is incomplete. Despite the duration of mankind's dependence on and curiosity about soil, exploring the diversity and dynamic of this opaque resource continues to reward. New and refreshing avenues of soil research are compelled by our need to understand soil in the context of climate change [3], greenhouse gases [4] [5], and carbon sequestration. [6]\n\nVasily V. Dokuchaev, a Russian geographer, is credited with identifying soil as a resource whose distinctness and complexity deserved to be separated conceptually from geology and crop production and treated as a whole.\n\nPreviously, soil had been considered a product of physicochemical transformations of rocks, a dead substrate from which plants derive nutritious mineral elements. Soil and bedrock were in fact equated. Dokuchaev considers the soil as a natural body having its own genesis and its own history of development, a body with complex and multiform processes taking place within it. The soil is considered as different from bedrock. The latter becomes soil under the influence of a series of soil-formation factors (climate, vegetation, country, relief and age). According to him, soil should be called the "daily" or outward horizons of rocks regardless of the type; they are changed naturally by the common effect of water, air and various kinds of living and dead organisms. [7] \n\nWhat is soil?\nSoil classification\nMain article: soil classification \nSoil classification is a contentious subject, from the structure of the classification system itself, to the definitions of classes and types, and finally in the application in the field. Every classification system starts with its own individual definition of soil. The essential problem is that soils do not reproduce or have DNA like living organisms, so no "objective" criteria can be used to choose among classifications. The most qualified specialists in the world can and do spend hours during a field trip at each soil profile, arguing about the classification. Yet, in a well-constructed system, the different names refer to similar concepts, so that interpretations do not vary widely.\n\nThe Unified Soil Classification System (or USCS) is used in engineering, geology and soil science disciplines to describe the texture, grain size,

Hydrology\n\nHydrology (from Greek: Yδρoλoγια, Yδωρ+Λoγos, Hydrologia, the "study of water") is the study of the movement, distribution, and quality of water throughout the Earth.

Environmental science is the study of the interactions among the physical, chemical and biological components of the environment; with a focus on pollution and degradation of the environment related due to human activities; and the impact on biodiversity and sustainability from local and global development. It is inherently an interdisciplinary field that draws upon not only its core scientific areas, but also applies knowledge from other non-scientific studies such as economics, law and social sciences. Physics is used to understand the flux of material and energy interaction and construct mathematical models of environmental phenomena. Chemistry is applied to understand the molecular interactions in natural systems. Biology is fundamental to describing the effects within the plant and animal kingdoms.

Earthship\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\nEarthships are earth-sheltered autonomous buildings made of tyres rammed with earth, which are usually arranged in a "U" or horseshoe shape. Each tyre is rammed full of earth using a sledge. Depending on its size and the soil density a tyre may weigh more than 300 pounds when properly prepared. Windows on the sunny side admit light and heat. The "U" shape of the structure faces South in the northern hemisphere, and North in the southern hemisphere, so that the house will catch maximum sunlight in the colder months.\n\nInternal, non load bearing walls, are often made of a "honey comb" of recycled cans separated by concrete. The walls are then usually thickly plastered, using the pull-tabs on the cans as a lathe to hold the adobe and stucco.\n\nThe roof of an Earthship is heavily insulated.\n\nIn mid-September Hurricane Marilyn roared through the Caribbean, destroying a quarter of the homes on St. Thomas, one of the U.S. Virgin islands. Full restoration of power took several months. Three thousand miles away, in Taos, New Mexico, Mike Reynolds, owner of Solar Survival Architecture, read the news and saw a demand for Earthships.

Well, "ology" means "study of" and "graphy" means "charting of."  I would say that all three of these concern earth and its inhabitants.

METEROLOGY AND CLIMATOLOGY ARE EARTH STUDIES THAT FOCUS ON\nON SYSTEMS OF PRESSURE THAT FORM ALMOST ANY IMPACT ON WEATHER AND CLIMATE. We study how systems move. And how earth and regional areas are changed by some storm half a world away. Composition You mean Density of storm matter or something else?

I have a PhD in geology and I don't know what "conserving the development of earth science" is.
