Will the earth be different if it had no radioactive materials?
of course
What does a radioactive dating estimate about the earth's formation with isotopes of uranium and thorium?
Radioactive dating estimate the age of rocks.
What evidence indicates that our solar system is about 4.5 billion years?
The main evidence is from radioactive materials on Earth, as well as their by-products.
Why is the Earth warm?
The Earth receives light, energy and warmth from the sun. Additionally, Earth still benefits from the decay of radioactive materials in its interior, and tidal distortions do their part in adding frictional energy.
What temperatures does the earth's core reach?
At the hottest point, the core inner core of the Earth is about 12500 degrees Fahrenheit due to radioactive materials that are constantly heating the Earth, just like a star.
Where does the heat in the center of the earth come from?
The heat at the centre of the earth is thought to be caused by the decay of radioactive materials, such as uranium, thorium and possibly an isotope of potassium. However this is currently not confirmed.
What on Earth can be reduced but never goes away completely?
Radioactive materials decay over half lifes but they never actually dissapear.
Does radioactive decay give evidence that the earth has changed?
Information on radioactive decay is used for radiometric dating. It can be used to determine the ages of rocks, fossils, and younger organic materials. Clearly, the earth has changed, and the dating of materials on the earth show this. In the really old times, the surface of the earth had no plants. Over time, the plants developed on the earth, and then came animals. Dominant forms came and went, and all this is in the record, dated to some extent by techniques that use radioactive decay rates. Even the rocks, untouched by life, have changed, and this also can be dated based on decay rates.
Which alkaline earth metals are radioactive?
Radium is the radioactive metal among alkaline earth metals.
How does nuclear power plant help us?
it help us by giving electricity . and when earth quack occurs it does not discharge harmful radioactive materials outside. there fore it stops and cool the earth quack
What are luminous materials?
Luminous means giving off light. Some materials that give off light are phosphorescent such as polycrystalline inorganic zinc sulphide and alkaline earth sulphides; some are radioactive such as radium and tritium.
What was thought to have been a source of heat when Earth first formed?
1.decay of radioactive isotopes 2.bombardment by meteorites 3.compression by overlying materials
