Las placas tectónicas son los fragmentos de la corteza terrestre que están flotando sobre las capas de roca fundida (conocida como la astenosfera). En la tierra existen al menos 15 placas principales y más de treinta placas de tamaño mínimo. Las placas están en constante movimiento por las corrientes convectivas de la astenosfera no que le da origen a fenómenos como los volcanes, los sismos, la formación de cadenas montañosas y dorsales oceánicas. De acuerdo a lo anterior, la respuesta correcta es la B. Placas tectónicas.
The correct answer is - 2. Earth's climates have changed and are likely to change in the future.
From what is known for the geologic past of the Earth, our planet's climate has been changing numerous times. The climate on the planet has varied from being predominantly wet tropical climate, to having ice ages, having multiple different climate types at the same time... The reasons for the changes in the Earth's climate are numerous, with the Sun's radiation, tectonic movements and activities, volcanic activity, outside influences like asteroid and meteorite collisions, the vegetation, and all of them have managed to create a very colorful climate history of the planet. This trend of climate change should continue in the future as well, as all of the aforementioned factors are still influencing the climate and on top of that the humans have become a factor in the climate change too.
