Verify the generalization Fields of Sciences Natural Sciences – deal with phenomena observable in nature Physical Science Physics – the scientific study of matter, energy force, motion, and the way they relate to each other. Chemistry – branch of science dealing with the structure composition, properties and reactive characteristics of substances, especially at the atomic and molecular levels. Meteorology – study of the atmospheric phenomena Volcanology – the scientific study of volcanoes, including their formation, signs of an eruption, and other aspects of volcanic activity. Mineralogy – the scientific study of minerals and how to classify, distinguish, and locate them Astronomy – the scientific study of the universe, especially of the motions, positions, sizes, composition, and behavior of celestial objects. Geology – the study of the structure of the earth or another planet, in particular its rocks, soil, and minerals, and its history and origins. Limnology – the scientific study of lakes, and other bodies of fresh water, including their physical and biological features.

The weather may be cool and dry, warm and humid, windy, cloudy, rainy or stormy. The average weather in a region over a number of years, usually decades. The climate of the Philippines is generally described as tropical. Weather Climate Elements of Weather degree of heat the force of air pushing on a unit surface amount of moisture in the air air in motion water that goes into the atmosphere is returned to the surface of the earth as rain, sleet, hail, snow, dew or frost. Temperature Air Pressure Humidity Wind Precipitation Types of Rocks formed through intense heat such as from volcanic magma deposited debris and consolidated by pressure Igneous (ex. granite) Sedimentary (ex. limestone) Metamorphic (ex. marble) from long term heat and pressure Weathering Erosion Deposition Compacting Metamorphism Melting Cooling solidifying the lowest and most dense layer within the stratosphere is the ozone layer which filters harmful radiations from the sun temperature decreases rapidly, coldest part temperature increases with height, solar radiation a region of electrically charged particles, or ions outermost region (outer space) & Rock Cycle The breaking down of rocks brought about by either physical or chemical means, giving rise to sediments or other rock fragments. The process by which rock fragments and sediments are carried along by such agents as wind and running water. The process by which rock fragments and sediments carried by agents of erosion are dropped or deposited in other places. The process by which rock fragments and other materials that accumulated, usually at the bottom of a thick column of water, get cemented together and harden into rock. A change in constitution of a rock brought about by pressure, heat and chemical reaction, resulting in a more compact and highly crystalline condition of the rock. To go from a solid state to a liquid state. Rocks formed by the cooling and solidifying of molten materials. UNIVERSITY OF THE PHILIPPINES LOS BAÑOS |UP CAGAYANOS 3
