Which example is a long-term environmental change? La Niña
El Niño
climate change
small asteroid impact

The correct answer would be Climate Change.

Profesional Explanation:

La Niña is incorrect because it is the cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns, which is not a long-term environmental change. El Niño is incorrect because it is an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, which is also not a long-term environmental change. A Small asteroid impact is incorrect because it will happen so suddenly, which is not a long-term environmental change.                                                                           Climate Change is correct because it will keep changing over time causing a long-term environmental change.

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.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
