Winds in our atmosphere are created as a result of which of the following processes?
shusha [124]

Answer:

<em>The correct option is D) Uneven heating of the air in the atmosphere</em>

Explanation:

Wind can simply be described as air which is moving or which is in motion. The uneven heating of the Earth's surface caused by the sun is the reason why winds occur. The difference in pressure of one area to another area causes the air to move and cause wind. The air tends to move from an area of higher pressure to an area of lower pressure and such is the movement of the wind.

Rock B reacts with hydrochloric acid. State the name of the rock B
choli [55]

Answer:

The sedimentary rock limestone which contains carbonate mineral Calcite and the metamorphic rocks which contain carbonate mineral Aragonite are the examples of rocks which react strongly with hydrochloric acid.

Explanation:

Rocks are naturally occurring structures formed on the Earth's crust and are composed of aggregate minerals. Classification of rocks: Igneous rocks - formed by cooling of magma on Earth's crust or seabed (basalts, gabbros, granite, etc), sedimentary rocks - formed over time by the accumulation of sediments from the weathering of existing rocks or fragments of minerals and organisms (mudstone, sandstone, shale, limestone, dolostone, siltstone, etc) and metamorphic rocks - transformed rocks formed from the existing rocks that are subjected to large pressures and temperatures (schists, gneiss, marble, etc).

The carbonate minerals like calcite, dolomite, aragonite, etc react with hydrochloric acid and release carbon dioxide gas bubbles. Calcite (calcium carbonate), which is found in igneous, metamorphic, and sedimentary rocks in a varying proportion reacts strongly with hydrochloric acid. So, the sedimentary rock Limestone which mainly contains calcite react strongly with the acid while Dolostone which mainly contains dolomite (calcium magnesium carbonate) reacts less vigorously. Another carbonate mineral aragonite, found in metamorphic rocks also reacts strongly with hydrochloric acid.
