If we can't dig to the center of the earth, how do we know that is down there?
because science has proven it by the heat of the equator found the earth
well if it wasn't i think we would cave in. we don't have to worry there will always be summer and winter seed time and harvest even though we can't see it we have a good idea that it is different layers of molten rock. this is supposition but where does lava come from, the gound. i hope this helps
because of off shore drilling into the plates of the earth showing the different layers we also would not have the rock cycle making rock from the middle of the earth
BCUZ WE R SMARTZEZ!
OK I WAS REALLY CONFUSED ON THIS QUESTION IN SCIENCE, YOU HAD TO FILL IN THE BLANKS MAYBE YOU COULD HELP!!! QUESTION:______ towards the poles,______ closer to the equator. this was my question i really need help hopefully you could help by march17, 2011. thanks coolP.
While we cannot physically dig to the center of the Earth due to the extreme heat and pressure, scientists have gathered significant evidence about the Earth's interior through several scientific methods. Here are a few ways we know what's beneath the Earth's surface:
1. Seismic Waves: Earthquakes generate seismic waves that travel through the Earth. By measuring and studying these waves with instruments called seismographs, scientists can analyze how they behave as they pass through different layers of the Earth's interior. The speed, direction, and intensity of these waves provide valuable information about the composition and structure of the Earth's core, mantle, and crust.
2. Volcanic Eruptions: Volcanoes are windows into the Earth's interior. When volcanoes erupt, molten rock called magma is ejected onto the surface. By analyzing the chemical composition of volcanic rocks, scientists can gain insights into the composition of the layers below, as magmas originate from deep within the Earth.
3. Mineralogical Studies: Minerals are crystalline solids formed within the Earth under specific temperature and pressure conditions. By studying rock and mineral samples obtained from mines, quarries, and even meteorites, scientists can deduce the conditions necessary for their formation, enabling them to infer the conditions and composition of the deeper layers of the Earth.
4. Gravity and Magnetic Field Mapping: Scientists map variations in the Earth's gravitational and magnetic fields to understand its internal structure. By measuring slight changes in the gravitational pull and magnetic field strength across different regions, researchers can estimate the distribution of mass and the presence of denser materials in certain areas, giving us insights into the Earth's interior.
Together, these methods, along with other scientific tools and theories, provide valuable information about what lies beneath the Earth's surface, even though we can't physically reach the center.
