What great geological event explains the formation of the great lakes the st Lawrence river system the Columbia snake river system and great salt lake?
During the last ice age, the great weight of the glaciers covering what is now The Great Lakes area actually lowered the land. It has been slowly rising up again since all the glaciers melted.
The melting of the glaciers provided tremendous amounts of water that scoured out pathways to the Pacific. They also filled the Great Lakes and overflowed to make rivers to the Atlantic.
The water flow created a river to The Great Salt Lake but not enough water enters it now to let it overflow to the sea. So the water just evaporates and keeps getting saltier.

What slow movement of continents?
The slow movement of continents is known as plate tectonics. This geological theory explains how the Earth's lithosphere is divided into large plates that float on the semi-fluid asthenosphere. These plates move and interact, leading to phenomena such as earthquakes, volcanic activity, and the formation of mountains.
What does the word continental fit mean?
"Continental drift" refers to the movement of continents over the Earth's surface due to the shifting of tectonic plates. This concept, proposed by Alfred Wegener in the early 20th century, led to the development of the theory of plate tectonics, which explains various geological phenomena such as earthquakes and mountain building.
When the landmasses of the British isles and Scandinavia are fitted together mountains chains and rock types?
The mountains chains and rock types in the British Isles and Scandinavia show geological similarities, indicating that these regions were once connected. This is supported by the theory of plate tectonics, which explains how continents have moved over time due to the shifting of tectonic plates. The geological history of these regions includes episodes of mountain building and volcanic activity, which have shaped the landscapes we see today.
Name geographers given to the movement of the continents?
Geographers call the movement of continents "plate tectonics." This theory explains how the Earth's lithosphere is divided into several large plates that move and interact with each other, leading to phenomena like earthquakes and the formation of mountain ranges.
How did the continents get their current positions?
The movement of tectonic plates over millions of years is responsible for the current positions of continents. Plate tectonics, a theory that explains how Earth's outer shell is divided into several plates that move across the Earth's surface, has caused continents to drift and collide, leading to the formation of the current landmass configurations.
What is the greatest geological discovery?
One of the greatest geological discoveries is the theory of plate tectonics, which explains the movement of Earth's lithosphere and the formation of continents, mountains, and oceans. This theory revolutionized our understanding of Earth's dynamic processes and continues to shape geological research and exploration.
Plate tectonics is a theory in what field of science?
Plate tectonics is a theory in the field of geology. It explains the movement of Earth's lithosphere (outer shell) and the resulting geological processes such as earthquakes, volcanic activity, and mountain formation.
What theory explains the formation and movement of the outer surface of the Earth?
The theory of plate tectonics explains the formation and movement of the outer surface of the Earth. It states that the Earth's lithosphere is divided into rigid plates that float on the semi-fluid asthenosphere below, causing them to move and interact at plate boundaries. This movement leads to various geological phenomena such as earthquakes, volcanic eruptions, and mountain building.

Which theory ties the fields of biology and geology together?
The theory of plate tectonics ties the fields of biology and geology together. It explains how the movement of tectonic plates has influenced the distribution of species, the formation of mountain ranges, and the evolution of habitats over geological time scales.
What slow movement of continents?
The slow movement of continents is known as plate tectonics. This geological theory explains how the Earth's lithosphere is divided into large plates that float on the semi-fluid asthenosphere. These plates move and interact, leading to phenomena such as earthquakes, volcanic activity, and the formation of mountains.
What theory explains the formation and movement of outer surface of the earth?

What theory explains formation and movement of the outer surface of the earth?
the theory of plate tectonics
What theory explains the formation and movements of the outer surface of the earth?
the theory of plate tectonics
What is plate tectonics context?
Plate tectonics is the scientific theory that describes the movement and interactions of the Earth's lithospheric plates. It explains the formation of continents, mountains, and ocean basins, as well as the occurrence of earthquakes, volcanic activity, and the distribution of mineral resources. Plate tectonics is a fundamental concept in geology and is used to understand Earth's geological history and predict future geological events.
What theory explains the movement of pieces of earths surface?
Plate tectonics is the theory that explains the movement of Earth's surface. It states that the Earth's lithosphere is divided into large plates that float on the semi-fluid asthenosphere below, causing them to move and interact with one another. This movement is responsible for various geological processes such as earthquakes, volcanic eruptions, and the formation of mountain ranges.
