Classification of Sedimentary Rocks (Part 1). Sedimentary rocks are classified based on their texture and composition. Detrital sediment has a clastic (broken) texture. Chemical and organic sediments have a non-clastic texture, and are classified based solely on their composition.
Galvanometer vs Ammeter. Ammeter and galvanometer are two devices that are used in the field of electronic and electrical measurements. Galvanometer is a very important device that is used to develop other measuring devices. It is also used to measure electrical currents. Ammeter is also a device that is used to measure electrical current.
An anemometer or windmeter is the device that measures wind speed.  They are usually divided into those that measure the wind's speed  and it's pressure. The first known ane â¦ mometer was described in 1450  by Leon Battista Alberti.nemometers can be divided into two classes: those that measure the wind's speed, and those that measure the wind's pressu â¦ re; but as there is a close connection between the pressure and the speed, an anemometer designed for one will give information about both.
