GENERAL GEOLOGY

Detailed explanation-1: -Scientists theorize that Earth’s largest physical features are created by? Plate tectonics: collisions between landmasses.

Detailed explanation-2: -Accretion theory explains how planets formed from the gas, dust, and ice revolving around an early sun. The dust collected into clumps and would stick together due to gravitational forces. Gravity is the force behind accretion that pulls particles of matter together.

Detailed explanation-3: -The earth has many major geographic features, with the most broad being the land masses known as continents and oceans that cover it.

Detailed explanation-4: -Earth is part of a larger system called the solar system. Earth has water, land, and air that make it suitable for plant and animal life. Which of the following is at the center of our solar system? Earth is part of a larger physical system that contains other planets, moons, and stars.

Detailed explanation-5: -Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth’s mantle.
