Humans have positively and negatively effected their habitats in a multitude of ways. The have helped their habitat in protecting endangered plant and animal species, cleanup of oceans, lakes, and land, and through planting trees.
Utilising the chart provided, I can see that every county listed here have a human development index (HDI) of 0.9 or above and also show wealthy countries such as the United States, Germany, Ireland and Norway.
Based on these results, I can confidently announce that the answer is D.
Answer:
The magma that melts in the upper mantle and erupts at the mid-ocean ridge has a different composition (higher in Ca, Mg, Fe and relatively lower in Si and Al) than the composition of the magma (more Si, Al, Na, K rich in relative terms) that built the continents. Melting different degrees (2%, 5%, 30%) of a rock with a mantle-like composition generates magma of different Al, Si contents. Continents grow at their edges by partial melting of oceanic crust that is being subducted, generating magmas of a somewhat more Si, Al-rich composition than the subducting slab itself. The chemistry and physics of melting a mixture of minerals rather than one homogeneous substance has the wonderful outcome of creating two distinct types of crust:
1..Location: reference of where a place is on earth, absolute location is latitude, longitude or an exact address, relative location is describing a place relative to other places
2..Place: physical and human characteristics of the location
3..Human-environment interaction: how humans and the environment affect each other
4..Movement: discussing the events of anything that moves across the earth (i.e. immigration of people)
5..Regions: characterized by a unified characteristic
Formal Regions are official boundaries like cities or states
Functional Regions are defined by connections
Vernacular Regions are perceived regions such as the south or the midwest!
