Metamorphic rock used to be what before?
a: igneous rock or sedimentary rock
b: magma
c : soil
d : none of the above
a: igneous rock or sedimentary rock
The most common elements in the crust are oxygen, silicon, aluminium, iron , calcium , sodium , potassium, and magnesium
Name 1 thing mudstone is made up of.
How are sedimentary rocks formed?
They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes.
Name 2 elements found on the lunar surface of the moon
Elements known to be present on the lunar surface include, among others, oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti)
How are dunes formed?
•A dune is a mound of sand formed by the wind, usually along the beach or in a desert. Dunes form when wind blows sand into a sheltered area behind an obstacle.
How are igneous rocks formed?
Igneous rocks are formed from cooled magma and are often either very rigid or porous depending on the place of cooldown.
name 1 way we come to know the minerals on mars
We have two primary sources of information as to what minerals make up rocks on Mars. The first is that we have identified meteorites from Mars that have landed on the Earth and we can directly study these and the minerals they contain.The second way we can determine minerals on other planetary surfaces, like Mars, is through imaging spectroscopy
What is erosion? and what causes it?
Erosion is the process by which soil and rock particles are worn away and the movement of those particles away from their source by wind, water or ice. Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice
Which Type of rocks face weathering?
Extrusive rocks
What is present on Mars' surface that causes is to be red?
Iron oxide
what happens after a sedimentary rock is exposed to burial, compression and high pressure
It turns into a Metamorphic rock
Example of a metamorphic rock
scarn, gneiss, quartzite, marble, schist, soapstone, and more
Name 2 elements found in the Martian crust
silicon, oxygen, iron, magnesium, aluminium, calcium, and potassium
What is the process after weathering?
Erosion and transportation
