Using a resource without limits--possibly using using a resource up completely.

describes energy sources that are still in development and are RENEWABLE.

The process by which soil is moved

the lowest layer of soil. It is a solid rock layer.

is the conversion of water from liquid to gas form by the exposure to heat.

To use or manage a resource wisely, to allow use but still keep resource going.

Energy that is produced from the sun

composes most of the trunk and
is made up of dead xylem cells. Like the
backbone that supports the tree.

It is made mostly of minerals, and most plant roots live here. This layer is also dark in color due to the amount of decaying plant and animal matter.

is the process of plants releasing water from their leaves.

To maintain a resource in an untouched state for continued survival.

Energy that is produced from moving or falling water.

Energy that is produced when ocean tides or waves change or move across the ocean or sea.

topmost layer of soil. It contains quite a bit of living material, plants, decaying leaves, needles, moss, and more. This layer is thin and very dark in color.

the condition of water for a particular use.

A resource that cannot be replaced after being used through natural or human processes.

Energy that comes from materials that were once living, like plants or animal waste.

the living
xylem that transports water and nutrients up
from the roots.

It is made of sand, silt and clay that have not been broken down all the way, so it usually has less organic material in it. It is also lighter in color.

As the vapor droplets become large, rain is formed and falls to the earth’s surface

A resource that can be replenished when used through natural or human processes.

Energy that comes from heat generated deep inside the earth from items like hot rocks, hot water and steam.

cell layer that produces
new bark (phloem) and new wood (xylem)
every year.

It is mostly rock that has been slightly weathered. Not many things live down here, except for the biggest tree roots.

As water vapor rises in the atmosphere, it begins to cool and turn back into water
