States that the Earth”s outermost layer is fragmented on large and small plates that are moving on another while riding atop a hotter and more mobile material known as the _____________.
ASTHENOSPHERE
Composed of the crust, mantle and core; and distinguished based on composition. (COMPOSITIONAL LAYERS, MECHANICAL LAYERS )
COMPOSITIONAL LAYERS
Consist of lithosphere, asthenosphere, mesosphere, outer core, and inner core. Distinguished based on rock strength and rigidity. (COMPOSITIONAL LAYERS, MECHANICAL LAYERS )
MECHANICAL LAYERS
According to RAISIN THEORY, the earth is likened to a grape that contracted into a raisin due to cooling process that occurred after the Big Bang 13.77 B years ago. (TRUE or FALSE)
TRUE
CLARENCE EDWARD DUTTON further explained the contracting Earth concept and proposed the term “ISOSTACY” which states that wherever equilibrium exists in the Earth’s surface, equal mass must underlie equal surface areas. (TRUE or FALSE)
TRUE
Plates are fit together like the pieces of a jigsaw puzzle and the movement ranges from less than 1 to more than 15cm per year. (TRUE or FALSE)
TRUE
ABRAHAM ORTELIUS suggested that America was originally connected to Europe and Africa and that the projecting parts of 2 continents would fit the recesses of America. (TRUE OR FALSE)
TRUE
Early geologist believed that the continents and the oceans had fixed geographical positions. (TRUE OR FALSE)
TRUE
ALFRED WEGENER noticed that the continents are fixed. He proposed the Continental Drift Hypothesis. (TRUE OR FALSE)
FALSE
The supercontinent broke apart because of various forces, which formed the separate continents we know today. (TRUE OR FALSE)
TRUE
The supercontinent broke apart because of earthquakes, which formed the separate continents we know today. (TRUE OR FALSE)
FALSE
The coastlines of continents fit together like a jigsaw puzzle. (TRUE OR FALSE)
TRUE
Identical fossils of organisms were discovered on different continents suggesting that a land was probably present in the past. (TRUE OR FALSE)
TRUE
Certain continents share common geological features, such as mountain ranges, rock types, minerals and resources. (TRUE OR FALSE)
TRUE
The continental Drift Hypothesis was subjected to criticism because the idea failed to explain the driving forces necessary for the “drift “ to occur. (TRUE OR FALSE)
TRUE
Wegener’s theory and sea floor maps were used to develop the theory of plate tectonics. (TRUE OR FALSE)
TRUE
