Detailed explanation-1: -It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.
Detailed explanation-2: -Earth has the largest known solid surface. The outer planets are fluid to the core and the inner ones are smaller. Earth has a predominantly nitrogen atmosphere. The gas in outer planets is mostly hydrogen, and Venus and Mars have mostly carbon dioxide in their atmospheres.
Detailed explanation-3: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption.
Detailed explanation-4: -The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth’s surface.
