Answer:
Volcanism: eruption of molten rock onto surface
tectonics: disruption of planet's surface by internal stresses
erosion: surface changes by water,wind or ice
Impact: impacts by asteroides or meteorites
Explanation:
Terrestrial planets have hard surfaces that can be reshaped by 4 major geological processes, that are:
- volcanism
- erosion
- tectonics
- impact cratering
Each of these processes is caused by different things. For e.g :
Volcanism happens when hot lava reaches the surface and give rise to volcanic planes e.g runny lava makes flat lava plains, while thickest lava makes steep stratovolcanoes
Erosion: is a geological process that removes rock, soil or dissolved materials and transport them by wind or water from one location of earth's crust to another. Example of erosion caused by ice, Glaciers carved by Yosemite Valley.
Tectonics: internal stresses in the earth caused by convection of mantle give rise to tectonic forces. Example compression forces give rise to mountain ranges. And valleys are formed at the point where a cryst is pulled apart
Impact cratering: This is caused when a meteorites or asteroides hits a planet's surface. Impact catering happened immediately after the solar system was formed.

Question: Which statement best explains why Earth’s outer core is in liquid form?
The iron-nickel alloy melts due to hot temperatures.
The outer core has a tarry consistency.
This region is less dense when compared to the mantle.
This region is under extreme pressure from the weight of other layers.
Answer:
The statement here that bet describes the Earth's outer core is in liquid form " The iron-nickel alloy melts due to hot temperatures."
Explanation:
The outer core of the Earth's is made up of fluid layer which is about 2400 km thick and basically made from iron as well as nickel alloy. This layer lies just above the solid inner core and below it mantle is present. The core of the Earth works like a furnace for the whole composition. It holds the intense heat as well as pressure that helps is maintaining the iron and nickel in the molten state.
Answer:
Nanotechnology helps to improve viscous fingering and the nano-particles can transmit through nanopores of sandstone which helps to increase the recovery by decreasing the surface tension between oil and water. The pore spaces are very fine so water molecules cannot penetrate through all of them in order to push the oil. This is why the nano-particles such as iron (Fe) and Silicon (Si) are used with distilled water. These particles can easily move through the interconnected pores and thereby pushes the oil to move out of it. It is a widely accepted concept in Enhanced Oil Recovery (EOR).
Answer:
It would seem that the answer in the question is correct
Explanation:
falls in the form of ice or snow is already unusable because of acid rain evaporates back into the atmosphere is taken up by plants or other organisms either runs off to form rivers or filters down into underground aquifers
