Granite is an intrusive igneous rocks made up of different minerals. Granite is made of crystals of biotite, feldspar (orthoclase and plagioclase) and quartz. As weathering acts on the rock it is broken down. Quartz is the most resistant of all the minerals that make up granite and so it will be left after thousands of years of exposure to the processes of weathering and erosion. The main component of sandstone is quartz and it is formed when the weathered sediments leftover from the weathering of the granite rock gets deposited and compacted by the process of sedimentation.
Quartzite is a metamorphic rock formed from sandstone. Sandstone can change into quartzite if it is exposed to extreme heat and pressure inside the crust.
Continental collision occurs when two continental plates move towards each other, each plate being dragged along by convection currents in the mantle. The extreme pressure and heat along these collision zones can cause metamorphism. Granite rocks at these zones can become foliated and change into gneiss.
The rock cycle shows possible paths and processes which crust material (rock)can be subjected to. The three main types of rocks represented on the the cycle are igneous, sedimentary and metamorphic. Igneous rocks are formed when magma or lava cools and hardens. Sedimentary rocks are formed when deposited sediments gets buried, compacted and cemented into hard rock. Metamorphic rocks are formed when preexisting rocks get subjected to extreme temperatures and pressure in the crust.
Answer:
Yes, One can is enough to cover the wall.
Explanation:
Given - Adalyn's mom is painting a wall in her bedroom with chalkboard
paint. If the dimensions of the wall are 12 feet by 9 feet and one
can of paint covers up to 110 square feet.
To find - Will one can be enough to cover the wall ? Explain.
Proof -
Given that ,
Dimensions of the wall are 12 feet by 9 feet .
Also,
One can of paint covers up to 110 square feet.
Now,
We know that Area of wall should be painted.
So, firstly we find the area of the wall.
Now,
Area = 12×9 feet²
= 108 feet²
⇒Area of wall = 108 feet²
Now,
As Area of the wall (108 feet²) < One can of paint covers (110 feet²)
∴ we get
One can is enough to cover the wall.
