Answer:
Avalanche
Explanation:
They mostly happen in mountainous regions where there is snow/ice and rocks. The ice underneath the boulders thaws momentarily due to the pressure of the rocks and ice above hence acting as a lubricant for the sliding down of the rocks down the mountain. Avalanches can be triggered by earthquakes, explosions, and etcetera.
Answer:
The amount of soil Marina will need to cover the garden is:
24 ft2
Explanation:
The reason behind this is that the formula to obtain the area of a rectangle is L multiplied by W where L is the length and W width. Knowing this we can substitute the letters by the size of each representation, meaning L=6 W=4 we multiply them and we obtain 24 ft2. Because when the feet are multiplied they become square feet. Also, because it doesn't matter the spaces used in the direction of the cartesian plane the numbers in means or width and length are positive to obtain the measurement of the area.
