describe three pieces of physical evidence that support the theory that earth has evolved over time. the three pieces of evidence must address the following: - cite one piece of evidence that includes fossils - cite one piece of evidence that includes plate tectonics - cite one piece of evidence that includes a catastrophic event

describe three pieces of physical evidence that support the theory that earth has evolved over time. the three pieces of evidence must address the following: - cite one piece of evidence that includes fossils - cite one piece of evidence that includes plate tectonics - cite one piece of evidence that includes a catastrophic event

Answer

Brief Explanations:

  1. Fossil evidence: Fossils show a progression of life - forms over time. For example, the fossil record of horse evolution shows changes in size, toe structure, etc. as horses adapted to different environments.
  2. Plate tectonics evidence: The movement of tectonic plates has led to the formation of mountains, creation of new oceanic crust, and the separation and joining of continents. For instance, the collision of the Indian and Eurasian plates formed the Himalayas.
  3. Catastrophic event evidence: Mass - extinctions like the Cretaceous - Paleogene extinction event, which wiped out the dinosaurs, are evidence of major changes on Earth. This event was likely caused by a large asteroid impact, which had far - reaching consequences for the evolution of life and the Earth's environment.

Answer:

  1. Fossil record of horse evolution shows life - form changes over time.
  2. Formation of the Himalayas due to plate tectonics.
  3. Cretaceous - Paleogene extinction event caused by asteroid impact.
