What else can I help you with?
What are two ways sedimentary and igneous rocks can be changed into metamorphic rocks?
Increase the pressure and temperature by burying them; or heat them with an igneous intrusion.
What was earth's first atmosphere was mostly a mixture of?
Earth's first atmosphere was mostly a mixture of gases such as hydrogen, helium, methane, and ammonia. Over time, volcanic activity released gases like carbon dioxide and water vapor, which changed the composition of the atmosphere.
What Gasses were present in the earth's early atmosphere?
The early Earth's atmosphere consisted mainly of carbon dioxide, water vapor, nitrogen, and smaller amounts of methane, ammonia, and hydrogen gases. Over time, the composition of the atmosphere changed due to processes like photosynthesis by early life forms.
How has the earths atmosphere changed over millions of years?
The earth's atmosphere has changed significantly over millions of years due to various factors such as volcanic activity, changes in the Earth's orbit, and the evolution of living organisms. For example, early Earth had a different composition with high levels of carbon dioxide and little oxygen. Over time, the atmosphere changed to its current composition with nitrogen as the dominant gas and oxygen supporting life.
How has the composition of earth's atmosphere has changed over three hundred of years what are the causes of this change?
Over the past 300 years, the composition of Earth's atmosphere has changed due to human activities like burning fossil fuels, deforestation, and industrial processes. These activities have led to an increase in greenhouse gases such as carbon dioxide and methane, which trap heat in the atmosphere and contribute to global warming. This change in composition has resulted in climate change and other environmental impacts.
When you run an electrical current through liquid water the water molecules are split apart to form oxygen and hydrogen gas this changed what properties of the water?
The splitting of water into oxygen and hydrogen gas changes its chemical composition but does not change its physical properties. The resulting oxygen and hydrogen gases can be collected separately but the water will still retain its characteristic properties such as boiling point, freezing point, and density.
How much does a loonie weigh?
Canadian loonies minted from 1987 to 2011 weigh 7 grams. The coin's composition was changed in 2012 resulting in a reduced weight of 6.2 gm.
How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
The makeup of rocks is changed during?
The make up is changed when the mineral composition undergo metamorphism.
What doesnt change during the composition of a substance?
The composition of a chemical compound is not changed during a physical change.
Does the Electron count change with the release of an alpha particle?
The number of electrons is changed.
What is matter that cannot be changed into a simpler form called?
An atom A fundamental particle
What is chemically changed the pan the egg or the fat when frying an egg?
The chemical composition was changed during frying.
What does a substance changed into when chemical change take place?
The reactants are changed in products having new chemical composition.
How does the boiling point of a hydrocarbon change in presence of hydrogen?
It can NOT be changed by the presence of hydrogen without chemical reaction.
How can your body composition be changed by altering two factors?
Diet and exercise.
What kind of rocks in which the structure texture or composition have been changed?
metamorphic
