Answer 2

а) Магматические горные породы бывают глубинными и излившимися. This statement is correct. Magmatic rocks can be classified into two main types: intrusive (or plutonic) rocks, which solidify beneath the Earth's surface, and extrusive (or volcanic) rocks, which solidify on the Earth's surface after volcanic eruptions.

б) Большинство магматических горных пород плотные и тяжелые. This statement is correct. Most magmatic rocks, such as granite and basalt, are dense and heavy due to their mineral composition and the cooling process they undergo. However, it's important to note that not all magmatic rocks are necessarily dense and heavy. Some volcanic rocks, like pumice, are actually lightweight due to the presence of gas bubbles trapped during the cooling process. [[2]]

в) Примером хемогенной осадочной горной породы является уголь. This statement is incorrect. Coal is not an example of a chemogenic sedimentary rock. Chemogenic sedimentary rocks are formed by chemical precipitation from solution, while coal is formed from the remains of plant material that undergoes compaction and chemical changes over time. Coal is actually an example of an organic sedimentary rock. An example of a chemogenic sedimentary rock is limestone, which forms from the precipitation of calcium carbonate from water. [[3]]

г) Метаморфические породы образуются только из магматических пород. This statement is incorrect. Metamorphic rocks can form from any type of pre-existing rock, including both magmatic and sedimentary rocks. Metamorphism occurs when rocks are subjected to high temperatures, pressures, and/or chemical changes, causing them to recrystallize and form new minerals. While some metamorphic rocks, such as marble, are derived from limestone (a sedimentary rock), others, like gneiss and schist, can be formed from pre-existing magmatic rocks like granite. [[4]]

In summary: - Magmatic rocks can be either intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface after volcanic eruptions). - Most magmatic rocks are dense and heavy, although there are exceptions like pumice. - Coal is not an example of a chemogenic sedimentary rock; it is an organic sedimentary rock. - Metamorphic rocks can form from any type of pre-existing rock, including both magmatic and sedimentary rocks.
