These are the particles of minerals and other rocks that make up a rock. What are grains? The look and feel of a rock’s surface What is texture? Igneous, sedimentary and metaphormic What are the three major rock groups? Crumbly, dark brown soil that is a mixture of humus, clay and other minerals What is topsoil? Loose layer of leaves and other plant material on top soil What is litter? The loose weathered material on Earth’s surface in which plants can grow What is soil? A layer of soil made mostly of clay and other particles, but with little humus What is subsoil? A layer of soil that differs from the layers above and below it What is soil horizon? Solid layer of rock beneath the soil What is bedrock? Soil made of about equal parts clay, sand and silt What is loam? Organisms that break down animal and plant remains and wastes What are decomposers? Process that breaks down rock through chemical changes. What is chemical weathering? Type of weathering in which rock is physically broken into smaller pieces What is mechanical weathering? Skeletons of living organisms that grow together to form a structure DAILY DOUBLE What is a coral reef? Two forces that can change rocks into metamorphic rock What are heat and presure? Anything in the environment that humans use What are natural resources? The management of soil to prevent its destruction What is soil conservation? A farmer plants different different crops in a field each year What is crop rotation? A thick mass of tougth roots at the surface of the soil What is sod? Organisms such as mold and mushrooms What are fungi? A measure of how well the soil supports plant growth. What is fertility? A type of rock that that forms from the cooling of molten rock at or below the surface. What is igneous rock? A type of rock that forms from an existing rock that is changed by heat, pressure, chemical reactions. What is metamorphic rock?
