Meteorology and Atmospheric Phenomena MCQ with answer and solution

Concept

An instrument that records the continuous variation of atmospheric temperature with time on a graph paper is known as a thermograph.

Step-by-step solution

1. Understand the requirement: The question asks for the name of the instrument that measures and records atmospheric temperature variation with time. 2. Analyze the options: A thermograph is a self-recording thermometer used to measure and continuously graph temperature changes against time. 3. Conclude the correct instrument name. Answer: (A) Thermograph

Explanation

A thermograph is a graph-producing instrument that continuously records temperature over a period of time. The prefix 'thermo' stands for temperature and 'graph' stands for writing or recording.

Why the other options are wrong

B: Hydrograph measures water flow or discharge over time in a stream or river. C: Seismograph measures ground motions caused by earthquakes. D: Thermohydrograph measures and records both temperature and humidity simultaneously.

Shortcut

Look at the root words: 'Thermo' means temperature, and 'graph' means a drawn record.

Common mistake

Confusing thermograph with hydrograph, which records water discharge or level in streams.
