.21 is the answer. It’s out of 100 and you move the decimal over two places to the left. 21 = .21 two places to the left
Overgrazing of drylands is a big one. An immediate reason is the removal of vegetation. This is caused by a few things like drought, climate change, tillage, deforestation, and overgrazing.
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
Answer:
Three characteristics of the sun are
Explanation:
- Solar being a giant yellow star filled with hydrogen and helium gases. It is one of the G type stars in the solar system.
- Sun consists of super magnetic storms that are the result of the solar flare that the sun creates due to its blasts of corpuscular energy.
- Sun has an 11-year cycle of sunspot activity. This cycle is a dominant feature of the sun's internal activity. Measured in wolf numbers.
- Solar activity causes auroras to light up the night sky on earth due to the solar winds which react with higher latitudes of the earth.
At some point in an earthquake, solid rock produces more shaking and building damage than loose, water-saturated soils. Stresses purpose rocks to deform; earthquakes arise as the rock can now not deform and ruptures
While earthquake surprise takes place in waterlogged soils, the water-filled pore spaces fall apart, which decreases the general volume of the soil. This technique increases the water pressure between character soil grains, and the grains can then move freely within the watery matrix.
But, earthquake shaking can disrupt the shape, the soil particles do not guide all the weight, and the groundwater strain starts offevolved to rise. The soil debris can circulate farther, and come to be entrained within the water--the soil flows. Liquefied soil will pressure open floor cracks so one can get away from the floor.
