A. Fill in the blanks:
The material in liquid form is called magma.
Magma is molten rock found beneath the Earth's surface. When it erupts through a volcano, it is called lava.
Most sedimentary rocks are formed under water.
Sedimentary rocks are typically formed in water environments such as oceans, rivers, and lakes where sediment is deposited and compacted over time.
Shale consists of fine grains of mud and clay.
Shale is a common sedimentary rock known for its fine-grained texture and composition primarily consisting of mud and clay minerals.
Feldspar and quartz are three main minerals in granite.
Granite is an igneous rock commonly composed of minerals such as feldspar, quartz, and mica.
Granite is mainly used in surgeries.
Apologies, but this statement seems incorrect as granite is not used in surgeries. Perhaps the intended word might be another mineral or tool material used in medical procedures.
B. Choose the correct answer:
Which of the following is a type of igneous rock?
(a) Granite
Granite is a well-known igneous rock formed from the cooling and solidification of magma beneath the Earth's surface.
Which of the following is a non-metallic mineral?
(c) Potassium
Potassium is not a metallic mineral. It is an essential element found in minerals like feldspar and is important for plant and animal life.
Which of the following is famous for its reserves of petroleum?
(a) Ankleshwar
Ankleshwar is a region in India known for its large reserves of petroleum, making it an important site for oil production in the country.
