Scientists theorized that the continents were once joined together even before they had modern evidence from rocks and fossils. Using only maps, they observed that -
continents with the most temperate climates were found near the Equator.
the oceans have become smaller throughout the history of Earth.
the shapes of continents appeared to allow them to fit together.
most of the larger land masses are in the Northern Hemisphere.
One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?
The ancient atmosphere in both places was identical.
The rates of weathering of rock are similar.
Fossil remains of the same land-dwelling animal.
Plants on both continents have similar flowers.
What is a destructive plate boundary?
Where two plates are converging or coming together and oceanic plate is subducted.
Where rising magma adds new material to plates that are diverging or moving apart
Where two tectonic plates slide past each other.
Where two plates of the same density are colliding and create fold mountains.
Which of these features is NOT found at a constructive plate margin?
Subduction Zone
Rising Magma
Plates moving apart
Volcanoes
