Answer:
False
Explanation:
The theory of continental drift was first proposed by geophysicist Alfred Wegener who believed that due to origin from same continent million years back, animal and plant species in current time though located on different land parcel have similarity in some or the other way.
However, after the acceptance of plate tectonic theory and series of magnetic surveys conducted in 1960, the idea of theory of continental drift strengthened and the wegner's theory was rectified as he proposed that continents do not originate from the ocean surface.

Answer:
High-level radioactive waste is derived from fission systems such as nuclear power plants.
Explanation:
When nuclear fuel is generated, the material that results from the process is still highly radioactive although it is not efficient to generate electricity. This byproduct is still harmful and it is labeled high-level radioactive waste. Although nuclear fuel is not the only one that generates this type of waste, it is the most common concern from the Manhattan project, for instance.
