Answer:
Hey mate hope it is helpful
Explanation:
11. igneous rock
Basalt is an aphanitic (fine-grained) igneous rock that is relatively low in silica and alkali metals. It has less than 10% feldspathoid by volume, with at least 65% of the rock consisting of feldspar in the form of plagioclase.
12. SIMA = silicon and magnesium.
13. limestone
When limestone, a sedimentary rock, gets buried deep in the earth for millions of years, the heat and pressure can change it into a metamorphic rock called marble.
14.stratosphere
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth's surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere
15. An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.
16.rain gauges
Instruments for measuring precipitation include rain gauges and snow gauges, and various types are manufactured according to the purpose at hand. Rain gauges are discussed in this chapter.
17.stratosphere
Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
18. The Ain-i-Akbari (Persian) or the "Administration of Akbar", is a 16th-century detailed document recording the administration of the Mughal Empire under Emperor Akbar, written by his court historian, Abu'l Fazl in the Persian language.
19.Manuscript:
Handwriting recognition (HWR), also known as Handwritten Text Recognition (HTR), is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices.
