Which statement is true about selective breeding and genetic engineering? A) Both genetic engineering and selective breeding aim to develop crops with desirable traits.
B) In genetic engineering, only traits that are natively found in the genome of the species can be
isolated and expressed.
C) In selective breeding, the desired genes can be directly manipulated or inserted into the DNA of
the organism.
D) In selective breeding, the potential list of insertions is not limited to those natively found in the
organism.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
