The early Earth was molten and remained so for at least several hundred million years. The first rock solidified from melt roughly 4.25 billion years ago based on radioactive decay dating methods. Because only rock and certain mineral assemblages can be dated scientifically, the age of the Earth must be older than the oldest terrestrial rock of Earth origin. The oldest rocks that have arrived on Earth from asteroid or meteor impacts have been dated to the presumed age of the Earth, roughly 4.567 billion years.

Why cant carbon 14 be used to determine fossil age of the fossil is several hundred thousand years old?

Carbon-14 dating is only effective up to about 50,000 years due to its short half-life of 5730 years. For fossils older than that, other dating methods like potassium-argon dating or uranium-lead dating are used, which have longer half-lives and can accurately determine the age of fossils that are several hundred thousand years old.


What characteristics of igneous rock make them good building materials?

Igneous rocks are generally strong, durable, and resistant to weathering, making them suitable for use as building materials. Igneous rocks are also versatile in terms of color and texture, giving architects and designers a wide range of options to choose from for construction projects. Additionally, their high melting points and ability to withstand high temperatures make them ideal for applications where heat resistance is necessary.


How do you mix sugar and oxygen to form carbon dioxide and water?

To mix sugar and oxygen to form carbon dioxide and water, the sugar (glucose) undergoes combustion in the presence of oxygen. This chemical reaction results in the production of carbon dioxide and water as byproducts. The reaction equation is: C6H12O6 + 6O2 → 6CO2 + 6H2O.


Why cant carbon dioxide be on the periodic table?

Carbon dioxide is a compound made of one carbon atom and two oxygen atoms covalently bonded together. The periodic table is a chart that lists elements, which are substances made of only one type of atom. Since carbon dioxide is a compound, it cannot be placed on the periodic table.


What is the differences between a carbon dioxide and carbon monoxide?

Carbon dioxide is made up of 1 carbon atom and 2 oxygen atoms. Carbon monoxide is made up of 1 carbon atom and 1 oxygen atom. Carbon monoxide is flammable whereas carbon dioxide is used to extinguish fires.

Why cant geologist use the carbon-14 method to date igneous rock?

Geologists cannot use the carbon-14 method to date igneous rock because carbon-14 dating is effective only for organic materials, such as wood or bone, that contain carbon. Igneous rocks, formed from the cooling and solidification of magma or lava, do not contain organic carbon and therefore do not incorporate carbon-14 during their formation. Instead, geologists typically use radiometric dating methods involving isotopes of elements like uranium or potassium, which are suitable for dating the age of igneous rocks.
