3. The seven Northeast states of new England and New York are the birthplace of land conservation in this country. Home to 35% of the country’s nearly 1,700 land trusts, the Northeast represents great tradition and accomplishment among land trusts of all shapes and sizes in the region. As of 2005, national state and local conservation groups saved 8.5 million acres in the northeast, over 12% of the region’s total land area.

4. Before Delaware was settled by European colonists, the area was home to the Eastern Algonquian tribes known as the Unami Lenape or Delaware throughout the Delaware valley, and the Nanticoke along the rivers leading into the Chesapeake Bay. The Unami Lenape in the Delaware Valley were closely related to Munsee Lenape tribes along the Hudson River. They had a settled hunting and agricultural society, and they rapidly became middlemen in an increasingly frantic fur trade with their ancient enemy, the Minqua or Susquehannock. With the loss of their lands on the Delaware River and the destruction of the Minqua by the Iroquois of the Five Nations in the 1670s, the remnants of the Lenape left the region and moved over the Alleghany Mountains by the mid-18th century.

5. Coal is a combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly sulfur, hydrogen, oxygen and nitrogen [ citation needed ]. Coal begins as layers of plant matter accumulate at the bottom of a body of water. For the process to continue the plant matter must be protected from biodegradation and oxidization, usually by mud or acidic water. The wide shallow seas of the Carboniferous period provided such conditions. This trapped atmospheric carbon in the ground in immense peat bogs that eventually were covered over and deeply buried by sediments under which they metamorphosed into coal. Over time, the chemical and physical properties of the plant remains (believed to mainly have been fern-like species antedating more modern plant and tree species) were changed by geological action to create a solid material. Coal, a fossil fuel, is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide emissions. Gross carbon dioxide emissions from coal usage are slightly more than those from petroleum and about double the amount from natural gas. [1] Coal is extracted from the ground by mining, either underground by shaft mining through the seams or in open pits.

6. The grand canyon is different from the northeast land forms. The northeast just has mounting’s not canyons. The grand canyon is about 277 miles long and 1 mile deep. The grand canton is in the southwest. The grand canyon is really big. Mrs. Perkins told me to do this.
