What are small channels called when are cut into earths surface when sheets of water flow around obstacles and become deeper?
it is rills
Why the surface layer of water in the poles is colder than the layer just below it yet the colder layer floats on top?
Due to the anamolous behaviour of water, the surface water being cooled by the external environment falls below 4C and begin to expand. when this surface water molecules expand they rise to the top due to a decrease in density as compared to the water below the surface. the cooler the temperature henceforth, the more the expansion of the surface water molecules till it solidifies to become ice. this surface ice then acts as an insulator and prevents the exchange of heat between the environment the water molecules just below it, thus maintaining the temperature of the water below the surface as constant.
How do intrusive igneous rocks become visible in the surface of earth?
it easly wears away and can travel by magma streams or rivers or could wear away into particles called protons and gets blown away by the wind.it can then land somewhere to slowly collect more particles to form an igneous rock in a random place
A place where magma pushes up on oceanic lithosphere?
A volcano is a place where magma reaches the earths surface to become lava. Which comes out of an opening that is called a fissure.
How does the earth stay at a constant temperature?
Earths core temperature is sustained by fissile materials slowly breaking down over time. This energy is dissipated to space and will eventually run out. Much like Mars, Earths core and mantle will become solid and Earth will lose its magnetic field. Earths surface temperature is a function of many variables. Among those variables are; The previously mentioned magnetic field limits solar radiation to the thermosphere, Greenhouse affects of diffuse materials in the atmosphere reflect heat back to the surface, And convective currents circulate heat between regions of different temperatures.
When rocks are subjected to weathering and erosion at the earths surface what type of rock do they become?
they die
How do plutons become visible at earths surface if they are formed underground?
erosion and plate tectonics
What caues surface water molecules to pull toeher?
It is called Cohesion. The process in which water molecules tend to become attracted to one another.
What happens to a rocks that are pushed under earths surface and become hotter and experience more pressure?
They become exposed to deformation, in a process called metamorphism.
What are small channels called when are cut into earths surface when sheets of water flow around obstacles and become deeper?
it is rills
How does water move in evaporation?
The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere. After evaporation water become a gas.
What are the small channels called which cut in to earths surface when sheets of water flow around obatacles and become deeper?
small channel
What happen to a substance during changes between solid a liquid?
The molecules of a solid are more tightly or securely fixed or fastened together. When heat is applied to the solid, the molecules become agitated or set in motion thus becomming more liquified.
What happen to the atom or molecules of a substance when it melts?
The intermolecular forces are weakened.
Why gravity becomes zero at equator?
Gravity doesn't become zero at equator, its value is roughly the same all over the earths surface.
How floods change earths surface?
floods destroy everything in its path. it causes rocks to break and become new land forms later.
Do gas particles become larger when dry ice changes into carbon dioxide?
The particles change from being tightly held in a solid to being free in the form of a gas; the molecules do not change size.
