Sahara is the answer! hope this helps! :)
The answer is to fill different niches.
<span>Adaptive radiation is the process of development of new forms
of organisms from an ancestral species. <u>When an environment changes or some new
niches open, speciation from the ancestral species occurs. </u>New species have morphological and
physiological adaptations which allow them to exploit a whole range of
divergent environment.</span>
The answer would be: false
Answer:
The answer is Option B: plate tectonics.
Explanation:
Plate tectonics is a theory about the structure of the earth's crust. In plate tectonics, the continents are viewed as a part of a system of rigid lithospheric plates which move slowly over the underlying mantle of the Earth. The model for plate tectonics builds on the concept of continental drift, which is an idea developed during the first decades of the 20th century. In continental drift theory, all the world's continents were once joined into a land mass that geologists have called Pangea during the late Paleozoic and early Mesozoic eras. It began to break up about 175 million years ago. In the beginning in the late Triassic, the continents began to break up with Laurasia comprising with what is North America and Eurasia and Gondwanaland which was South America and Africa, India, Arabia, Antarctica, and Australia. The shift in plates and their movement create mountain ranges and continents form and move to different latitudes that change the climate as these land masses moved.
Answer:
E is correct for sure but I'm not sure with D.
Explanation:
according to Alfred wegener all the continents were joined but later separated after million years so the coast of South America and West coast of Africa must be like a puzzle pieces when matched it must join.
the question also says that he uses geological and fossil evidences so I thought another answer must be from fossils so that's why it's either C or D.
