Pedalfer is composed of aluminum and iron oxides. It is a subdivision of the zonal soil order comprising a large group of soils in which sesquioxides increase relative to silica during soil formation. Pedalfers usually occur in humid areas.

Q10. Gravitational force is maximum at which of the following place?
निम्नलिखित में से किस स्थान पर गुत्वाकर्षण बल सबसे अधिक है?
The gravity of Earth, which is denoted by g, refers to the acceleration that is imparted to objects due to the distribution of mass within the Earth. Earth’s gravity is stronger at the poles than the equator for two reasons:
The centrifugal “force” cancels out the gravity minimally, more so at the equator than at the poles.
The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
Q11. Which of the following device is used to measure humidity?
निम्नलिखित में से कौन सा यन्त्र का प्रयोग आद्रता मापने के लिए किया जाता है?
Humidity is the measure of the amount of moisture in the air. A psychrometer is an example of a hygrometer. A psychrometer uses two thermometers to measure relative humidity; one measures the dry-bulb temperature and the other measures the wet-bulb temperature.
