What physical process changed the geological area and composition of the Earth's oceans shown in the two pictures below?
The geological area and composition of the Earth's oceans have been significantly altered by plate tectonics and volcanic activity. These processes can lead to the formation of new oceanic crust, the alteration of seabed topography, and the release of minerals and gases into the water. Additionally, erosion and sedimentation play a role in changing the composition of ocean waters over time. Together, these factors continuously reshape the geological features and chemical makeup of the oceans.

What doesnt change during the composition of a substance?
The composition of a chemical compound is not changed during a physical change.
Is a glass tube physical or chemical?
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
What is the composition of the materials during physical change?
During a physical change, the composition of the materials remains the same. The change only affects the physical properties of the substance, such as its shape, size, or state of matter, without altering its chemical composition. This means that no new substances are formed during a physical change.
Why is the melting point of table salt a physical property?
During melting the chemical composition of NaCl is not changed.
What is the physical structure of the earths rock is changed by?
The physical structure of the Earth's rocks is changed by geological processes such as weathering, erosion, and sedimentation, as well as tectonic activities like folding, faulting, and volcanic eruptions. These processes can alter rock composition, texture, and structure over time, leading to the formation of different rock types, such as sedimentary, metamorphic, and igneous rocks. Additionally, human activities, such as mining and construction, can also impact the physical structure of rocks.

Why is the boiling of water a physical reaction and not a chemical reaction?
During boiling the chemical composition is not changed.
Why is the melting point of table salt a physical property?
During melting the chemical composition of NaCl is not changed.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
What is chemical and physical reactions?
A physical reaction is were the current substance can be changed in state and then changed back easily to it's previous state, a chemical reaction is the opposite, it is difficult to change it back to its previous state.
