two, two words put together
Tac welding is not a specific material. Tac welding is a form of welding, that welder's use in order to hold two pieces' of metal together to get a proper fit. The tac weld can be easily broken if the two pieces' of metal aren't in the right place. So if you tac weld anything, the filler is going to be whatever material you are welding.
Scissors
A screw.
Usually by bolting or welding them.
Africa and South America are often cited as having coastlines that fit together like puzzle pieces. This is known as the continental drift theory, suggesting that these continents were once connected.
something about somedinosaurs found in both continents and they cant swim all across the ocean.
Two reasons the continents didn't fit perfectly together while they were Pangaea are the effects of erosion and sea level changes. Over time, erosion of the coastlines and movement of tectonic plates caused the shapes of the continents to change. Sea level changes due to factors like glaciation also altered the coastlines and made the fit less perfect.
Alfred Wegener proposed that the continents of South America and Africa looked like they could fit together like puzzle pieces to form a single landmass called Pangaea.
The two smallest continents by land area are Europe and Australia. The two continents that fit the definition of an island are Australia and Antarctica.
the two continents are australia and antarctica
Africa and South America have coastlines that fit together like puzzle pieces, particularly along the Atlantic Ocean. This observation supports the theory of continental drift and the idea that these two continents were once connected as part of the supercontinent Pangea.
South America and Africa fit together like a puzzle. This matching pattern is known as the continental drift theory, which suggests that the continents were once part of a single landmass called Pangaea.
One main evidence is the fit of the continents' coastlines, particularly the fit of South America and Africa. Fossil evidence of similar species found on different continents also supports the idea of continental drift. Additionally, the matching geological features and rock formations across continents provide further evidence for the theory of continental drift.
The continents with the most obvious fit of coastlines are Africa and South America. This is known as the theory of continental drift, where it is believed that these continents were once connected as part of the supercontinent Pangaea. The coastlines of these two continents appear to fit together like pieces of a puzzle, providing evidence for the theory of plate tectonics.
South America and Africa fit together like puzzle pieces due to the complementary shapes of their coastlines. This observation contributed to the development of the theory of plate tectonics, with the concept of these continents once being part of the supercontinent Pangaea millions of years ago.
Alfred Wegener believed that South America and Africa fit together like a puzzle, forming a larger landmass called Pangaea. He proposed the theory of continental drift, suggesting that the Earth's continents were once joined together and have since moved apart.
