a ostrich egg
yes, Mars did look like the earth. It had liquid water on it. It does not look like earth anymore because the core of the planet cooled down and when that happened it lost its magnate field. The core cooled down faster than earth because mars is small the earth. The earth and mars will die the same way.
because it looks like hunter.(???) It is theorized that the moon has a solid core of iron generating little to no heat. As there have been no techtonics recorded, it is also theorized that the moon has no form of molten mantle. In all other respects the moon is composed of elements similar to that of the earth.
Some would say gravity, but since the center of the core is effectively null gravity due to all of the mass of the earth located equidistant from it in all directions, then I think the pressure at the core is considerably lower than others estimate. probably the highest pressures would not be at the core, but at some point between the core and the mantle, some of this depends on a liquid core or a solid core model...how can a solid be pressurized internally if it is free-floating at the center of the mass of a planet? You know, they tell us that the Earth's core is molten iron and nickel and that it is a liquid core since the Earth has a strong magnetic field....but don't you remember learning that heat destroys magnetism? And look at the magnetic field lines in the arching solar flares from the sun itself! How can these be magnetic if heat destroys magnetism....why is the sun magnetic if it is made primarily of hydrogen and helium? One scientific question always seems to lead to others...seems like a fractal progression....
Because when I look up from the Earth, the surface of the Moon looks like nothing on Earth.
Mars' core is made primarily of iron and sulfur. It has a solid core like Earth that is wrapped in a mantle made of silicates. A mantle comprised mainly of silicate and a thick crust which appears to be basalt thinly covered in iron-oxide dust. Mars composition is quite similar to Earth's. Its core is mainly made from iron and sulfur. It is surrounded by a mantle of silicates and this is wrapped with a crust of basalt and iron oxide. Wow the previous answer was just bad. Mars much like earth has a core that is predominately Nickle, Iron and Sulfur. The mantle is likely Silicon, Oxygen, Iron, and Magnesium. The crust is volcanic rocks. Since the core is completely solid unlike earths there is no dynamo effect to create a magnetosphere which causes the surface of Mars to be highly irradiated at times due to solar radiation.
its like earth's core
Just like Earth Mercury has 4 main layers, The inner core, the outter core, and the mantle, and the crust.
The Earth's core is composed of two layers: the outer core, which is liquid iron and nickel, and the inner core, which is solid iron and nickel. These layers are surrounded by the Earth's mantle and crust. The inner core is about the size of the moon and is extremely hot, reaching temperatures of about 5700 degrees Celsius.
the inner core
yes, Mars did look like the earth. It had liquid water on it. It does not look like earth anymore because the core of the planet cooled down and when that happened it lost its magnate field. The core cooled down faster than earth because mars is small the earth. The earth and mars will die the same way.
The Earth's core is composed mainly of iron and nickel, with the outer core in a liquid state and the inner core in a solid state. It is approximately 2,900 km (1,800 miles) below the surface and is extremely hot, with temperatures reaching up to 5700°C (10,300°F).
The inside of Earth is made up of several layers: the inner core, outer core, mantle, and crust. The inner core is solid iron and nickel, while the outer core is liquid iron and nickel. The mantle is a semi-solid rock layer, and the crust is the solid, outermost layer that we live on.
It is a core which is made up of ice. It is cold
no it doesnt it only lookes like that when the suns near it
The Earth's interior consists of several layers, including the solid inner core, liquid outer core, mantle, and crust. The inner core is solid iron and nickel, while the outer core is liquid molten metal. The mantle is made up of solid and molten rock, and the crust is the Earth's outermost layer, varying in thickness beneath the continents and oceans.
Because the inner core of Earth is a solid sphere suspended in the gravitational center of the liquid outer core. Both cores are an alloy made up of mainly nickel and iron. This alloy is conductive and the inner core is spinning at a different rate in the outer core. This difference in angular momentum creates a huge electric dynamo, which in turn creates a strong magnetic field. If and when the core of the earth completely cools to a solid the dynamo effect will cease, and our magnetic field will collapse. If there is any atmosphere that remains at this time, it will be boiled off into space by our suns solar wind. The water will eventually follow the way of the atmosphere and the surface of earth will begin to look like the surface of Mars.
It is a very bright mass of roiling gas or plasma.
