by tracking sea ice minimum and sea ice maximum, scientists are able to: determine future movements of the jet stream. better protect naval fleets during wartime. develop effective water policies for western countries. measure the effect of greenhouse gases. conserve the habitats of polar bears.

preservation because he preserves part of the land and preserves means save

explanation:

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
