Why are these planets so different? To answer this, we must start with an understanding of the processes that cause planetary surfaces to change: volcanism, tectonics, erosion, and impacts. Watch the AstroTour Animation on Processes that Shape the Planets, and use what you learn to match each item to the corresponding process.

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:

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.

*Volcanism: massive layer of planetory body

*Erosion: wind,air

*Impact:Micrometeoroid.

Explanation:

ANSWER A:

*Volcanism: massive layer of planetory body

*Erosion: wind,air

*Impact:Micrometeoroid.

The surface of the planet can be detected by all the process it experienced all through its existence, and each of these process is developed by different entities.

QUESTION 2

ANSWER: There would be approximately same number of craters per area by all the planets.

REASONS: provided that there are same frequency for the impact,then the number of craters in the surfaces of the terrestrial planets is the same

ANSWER:3: The left surface has gone through less vocalism or erosion compare to right surface.

REASONS: the image on the left and the right image still have higher density which implies the crater is no more available. Meanwhile when there's erosion or volcanism, the two parts suppose to have same crater.

ANSWER 4: There's more density with surface that are older.

ANSWER 5: The size

ANSWER 6: The planets is usually in molten form when erupted then solidify which causes volcanism

ANSWER 7

The earth's moon is unique in that it is much larger than the moons of the of other inner planets.

ANSWER 8:

C-type asteroid has the same object type as Phobos and Deimos

ANSWER 9

Crust

ANSWER 10

The impact of the reminant surface of the earth is accumulated to form out the moon.
