Answer:
choosing one cereal over another and losing the chance to buy the other
Explanation:
Opportunity cost is the choice sacrificed for another alternative.
Our wants according to economics are unlimited. The resources to meet these unlimited wants are also scare. Production is limited by availability of resources.
Due to limited resources, we have to choose more important needs over the other. Often times, a scale of preference is drawn for our wants.
The cost of choosing one particular commodity over another is called the opportunity cost.

The three main types of rocks are:
1. Igneous rock
2. Sedimentary rock
3. Metamorphic rock
They are classsified by their formation :
Igneous rock- This type of rock is formed due to volcanic activities, and under this type of rock, it is seperated into volcanic rock and plutonic rock.
Volcanic rock is also called intrusive igneous rock, where the magma filled the cracks below surface and cools down without meeting the air. One of the example if this kind of rock is granite.
Plutonic rock is also known as extrusive igneous rock where volcanic eruption occurs and the lava cools down after being exposed to the air. One of the example is tuff.
Sedimentary rock- These kind of rocks are formed due to the accumulation of sediments overtime. Rocks are also divided into two types under this catagory, namely clastic and non-clastic sedimentary rock.
Cladtic sedimentary rock - It is where the particles of sediments gets compacted due to accumulation, and the rock is usually coarse grained with different size of particles, for example, breccia.
Non-clastic on the other hand, are formed by organic substance that existed for a very long time to become rock, for example, coal is a kind of rock that is formed by organic substances under million years of accumulation. It is posible that fossil will be found.
Metamorphic rock- These type of rocks under goes extreme high temperature or compaction to form a new kind of rock from their parent rock. For instance, igneous rock will turn into marble under high temperature.
Hope it helps!

Answer:
The bends causes the overlaying of a crustal layer upon other layer. It results the formation of mountain on the overlying layer.
Explanation:
The big bends on the earth crust are the big faults. This fault formed due to the overlaying of a layer with other layers. The overlying crustal layer has deposits of lands on it and forms big mountains. This is a continuous and slow process. Sometimes the tectonic plate movement results in a sudden rise of some lands, and this forms new tabletop land and also dome mountains. The mountains are always formed due to the fault of the crust which are the bends on the earth. The mountains also formed due to a volcanic eruption. Such mountains are known as volcanic or igneous mountains. This is the very reason the mountains form around big bends
