Water.
The Earth is an open system with respect to matter because it exchanges matter with its surroundings through processes like volcanic eruptions, meteorite impacts, and material entering and exiting the atmosphere. This continual exchange of matter allows for the cycling of nutrients and elements that sustains life on Earth.
Earth is an open system with respect to energy, as it receives energy inputs from the Sun in the form of sunlight and radiates heat back into space. Additionally, Earth is an open system with respect to matter, as it exchanges gases, water, and nutrients with its surroundings through processes like photosynthesis, respiration, and the water cycle.
The Sun is entirely plasma, which is a form of matter in which the electrons have been stripped away from the atomic nuclei.The Earth and Moon are mostly rock.
the Earth has 3 main layers the Atmosphere, Crust, and Mantle/Core the Atmosphere is made up of mostly gas the Crust is made up of (mostly) solids and the Mantle/Core is filled mainly with liquid metals
Our earth is mostly made up of silicon oxide (sand) and magnesium oxide, extending from the outer core to the crust. The inner core is mostly iron, enriched to 4% nickel. About 70% of the surface is covered with water.
Earth is an open system when it comes to energy, as it receives energy in the form of sunlight from the sun and emits energy back out into space. This constant input of energy drives the Earth's climate, weather patterns, and sustains life on the planet.
The surface of earth is covered mostly by water.
Earth is covered mostly in water, but is not made up mostly of water. Most of earth is made of rock.
The Earth is mostly considered a closed system because it exchanges energy with its surroundings but not matter. However, it can also be viewed as an open system when considering the input and output of matter through processes like meteorite impacts or atmospheric escape.
The Earth and the Moon are not made mostly of gas but the Sun is.
Space is not completely empty; it contains matter in the form of gas, dust, and other particles. However, space is mostly a vacuum, meaning it has very low density compared to Earth's atmosphere.
no it's mostly filled with empty space.
