Question

Unscramble the following words to form a coherent sentence about Earth's history: "landmasses plate prove on move surface that tectonics and drift the that and Pangea continental Earth's existed."

Answer 1

The sentence 'Plate tectonics and continental drift prove that landmasses move on Earth's surface and that Pangea existed' encapsulates the theory of plate tectonics and Alfred Wegener's idea of continental drift, which proposed that all continents were once part of a supercontinent called Pangea, backed by various geological evidence.

Step-by-step explanation:

The unscrambled sentence describing Earth's history with respect to plate tectonics would be: "Plate tectonics and continental drift prove that landmasses move on Earth's surface and that Pangea existed." This describes the fundamental principle of geology known as plate tectonics, which explains the movement of Earth's lithosphere.

German scientist Alfred Wegener proposed the idea of continental drift in 1915, suggesting that continents once formed a supercontinent named Pangea.

He supported his hypothesis with evidence from the shape of continents, matching fossils, mountain ranges, and paleoclimates. However, his theory wasn't widely accepted until the mid-20th century, when further studies expanded upon his ideas and the mechanisms driving the movements were better understood.
