Cornstarch and water create a non-Newtonian fluid known as oobleck, which behaves differently under stress, becoming more solid when pressure is applied. In contrast, Earth's mantle is composed of semi-solid rock and minerals that can flow slowly over geological timescales due to heat and pressure, but it does not exhibit the same immediate change in viscosity as oobleck. While both materials can flow, the mechanisms and conditions governing their behavior are vastly different. Additionally, Earth's mantle is a complex mixture of silicate minerals, whereas cornstarch is a carbohydrate, and water is a simple molecule.

How is a mixture of cornstarch and water similar to the earth's mantle How is it different How might the plasticity of the mantle influence the movement of the earth's lithospheric plates?
Both the mixture of cornstarch and water and the Earth's mantle exhibit a semi-fluid behavior known as plasticity, allowing for flow over time. However, the mantle is composed of solid rock material whereas the cornstarch-water mixture is composed of two distinct phases. The plasticity of the mantle influences the movement of Earth's lithospheric plates by allowing them to slide and interact with each other along plate boundaries due to the mantle's ability to deform and flow.
Is cornstarch mixed with water a chemical reaction?
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
Will cornstarch dissolve in water?
Yes, cornstarch can dissolve in water to form a mixture called a suspension. When stirred, the cornstarch particles disperse in the water but do not fully dissolve like sugar or salt would.
What is the chemical formula for cornstarch added to water?
Well, there is no chemical reaction, really, since the cornstarch still remains cornstarch. (and if you dry it, it becomes cornstarch again) It's just that the cornstarch lightly bonds to the water which then lightly bonds to other cornstarch, creating a net-like substance. This net is easily broken and made, thus increasing the viscosity of the fluid and adding some other interesting properties to it as well.
Is cornstarch dissolving in water a endothermic or exothermic reaction?
When cornstarch dissolves in water, it undergoes a process that is generally considered endothermic. This means that it absorbs heat from the surroundings, which can lead to a slight cooling effect in the mixture. The interaction between cornstarch molecules and water requires energy, resulting in this heat absorption. Therefore, the dissolution of cornstarch in water is characterized as endothermic.

Can cornstarch dissolve in oil?
Cornstarch does not dissolve in oil; rather, it is hydrophilic and dissolves in water. When mixed with oil, cornstarch may form a suspension or paste, but it won't dissolve like it does in water. The two substances have different polarities, which prevents cornstarch from fully integrating into the oil.
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
Why is water cooler near earths poles?
because they are different parts of the earths hemispheres.
How are convection currents in water like convection currents in earths mantle?
They both are the same because they are currents that move like waves
How are earthquakes eruptions different from volcanoes?
Earthquakes do not exactly erupt. Earthquakes are caused by the movement the Earth's tectonic plates. Yes, Earthquakes can contribute to the eruptions of Volcanoes because when one plate goes under the other water could be taken with it down into the Mantle. The water and sometimes air when is in the mantle is forced to find an exit and those exits are Volcanoes. When they go into the Volcano pressure builds up and the Volcano erupts. So really Earthquakes are caused by the movement of the Earths tectonic plates while Volcanoes are caused by a build up of pressure in the Earths Mantle.
Is cornstarch soluble?
Cornstarch is not soluble in water; instead, it forms a suspension when mixed with water. When cornstarch is added to water, it doesn't dissolve but can create a thick mixture due to its ability to absorb water and swell. However, when heated, cornstarch can undergo gelatinization, which allows it to thicken liquids more effectively.
