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.

<em>I implore you all to rise up against this enemy of ours.</em>
Answer:
The flow velocity, or speed of flow, can influence the shape and rate of erosion of a river system. The cross-sectional shape of a river dictates how much friction will impact the flow of water within a river. Finally, the sediment load, or the amount of rocks and soil in the river, impacts its flow velocity and shape.The velocity of a river is determined by many factors, including the shape of its channel, the gradient of the slope that the river moves along, the volume of water that the river carries and the amount of friction caused by rough edges within the riverbed. Access to a fresh water supply is affected by the following factors: Climate – low levels of rainfall and high temperatures lead to water deficits . When rainfall is low, there is less water available. When temperatures are high, water evaporates and so there is less available to use.
Answer:
preservation of original remains, permineralization, molds and casts, replacement, and compression.
Explanation:
Rock formations with exceptional fossils are called very important for scientists to study. They allow us to see information about organisms that we may not otherwise ever know
Answer:
A. are brought from the mantle to the surface in magma that hardens into kimberlite
Explanation:
Diamonds are brought to the surface from the mantle in a magma that is known as the kimberlite. This kimberlites is rich in gases and it is an igneous rock that has the following minerals,olivine, phlogophite, serpentine etc.
The origination of diamonds in the mantle happens as carbon transformation occurs due to heat and pressure occurs. The kimberlite pipes and what brings the diamonds to the surface
