What is the structure of the earth starting from the inside (7) 4. Describe what hap- pens at a constructive plate boundary and the landforms associated with it (2) Give one examples of destructive bound- aries 1. Divergent/Constructive (Move away from each other) 2. Convergent/Destructive (Move towards each oth- er...

1. Anthropogenic derived from human activities 2. Erosion The process by which wind, water, ice, or gravity transports soil and sediment from one location to another 3. Runoff Part of the water cycle where an excess of water runs down and does not sink into the soil and eventually makes it to the rivers, lakes, and oceans. 4. Denitrification process in which fixed nitrogen compounds are con- verted back into nitrogen gas and returned to the atmosphere 5. Nitrification ammonia (NH3) is conv...

1.A(n) energy resource is one that is consumed faster than it can regener- ate. 2. When converting energy from one form to another, . 3. About 90% of the energy used by an incandescent lightbulb is . 4. Kinetic Energy Potential Energy 5. When considering the conversion of energy from moving water to electrici- ty, put the following steps in the prop- er order. 6. Inferred energy can also be calledheat 7.When comparing an incandescent and an LED lightbulb, the lightbulb is more efficient...

1. superposition The principle that any given rock layer is probably older than those above it and younger than those below it 2. continental crust Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). 3. oceanic crust Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Com- posed of basalt. 4. mantle Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and silicon-o...
