Geological Formation of Haryana
The geological formation that resulted in the formation of Haryana state starts from the Mesozoic-Cenozoic era. The Mesozoic-Cenozoic era saw the emergence of rivers, rivulets, hills and hillocks. The state is covered by Quaternary Sediments of alluvial origin to a large extent.
Geographical Divisions of Haryana
Around 93% of the land area in Haryana consist of plains. Rest of the area consist of low hills. Basically, there are four geographic division on the basis of relief features in Haryana. But on the basis of theoretical importance and land area, it can be divided into eight geographic divisions. These are as follows : The Lower Shivalik Hills
The Shivalik hills are structure of Himalayas which formed as the third and last upliftment of Himalayan mountain in the post-Pliocene Age. The Shivalik hills cover the North-Eastern part of Haryana.
These hills form the outermost part of the Himalayas. Average elevation of these hills is 600-1500 m. It covers mainly the district of Ambala, Panchkula and Yamunanagar. These hills are the source of rivers like Saraswati,Ghaggar, Tangari and Markanda. Panchkula is the only hill station situated in these hills. Kalka and Pinjore are the two famous valleys of this region.
Morni hills are a branch of Shivalik hills and lies in the district of Panchkula, with an average elevation of 1065 m. The highest point on these hills is the Karoh peak (1467 m). Karoh peak is also the highest point in Haryana. Tipra hills form the Northernmost boundary of Haryana adjoining Nahan, a place on the border of Himachal Pradesh. Tipra hills lie North of the river Ghaggar in Panchkula district.
These plains lie in Ambala, Panchkula and Yamunanagar districts as an extension of the Shivalik hills. These plains extend upto 25 kms beyond the Shivalik hills. These plains are locally known as Ghar. Average elevation of these plains is 300-375 m.
These plains are drained by Ghaggar and Yamuna rivers and thus also known as Ghaggar-Yamuna Plains.
This region extends in between the rivers Markanda, Saraswati Chotang and Yamuna. Kaithal, Ambala, Kurukshetra, Yamunanagar, Karnal, Jind, Panipat, Rohtak and Sonipat lies in this region. Yamuna river forms the Eastern boundary and runs from Yamunanagar to Faridabad to make the flood plains. These plains are divided into two parts, the higher one is called Bangar, while the lower one is called Khadar.
These plains are made up of sand, clay, silt and hard calcareous gravels locally known as Kankars. Average elevation of these plains is 220-280 m. The trees of Shisham, Peepal, Banyan,Mango,Neem and Jamun are found here.
These plains are made by Yamuna river and its tributaries in the Eastern region of the state.Marshy lands are also found within these flood plains. Flood plains made by Markanda river is called Bet and flood plains made by Ghaggar river is called Nelli.
It lies in the South-Western part of the state made up of extended sand dunes upto several kilometers. Average elevation of these plains is 200-300 m. These sand dunes are the result of the deposition of sand in this area which is carried by the hot dry winds blown from Rajasthan. These sand dunes move with the flow of wind. In Haryana, it covers the parts of Sirsa, Fatehabad,Hisar, Bhiwani,Mahendragarh, Rewari and Nuh districts and lies along the border with Rajasthan. This plain region is infertile due to sand dunes, but a green belt is planted here that helps to check the further extension of these dunes. Rainfall is very low in these plains.Ground water of the region is far below the surface and very salty in taste. Keekar, Khair, thorn and other thorny shrubs grow here.
The Aravalli Hills
These hills lie in the Southern part of Haryana. These are an example of residual hills in India. These hills are locally known as Mewat hills. These hills are extended approximately 800 km from North-West to South-West across states of Rajasthan, Haryana and Gujarat. Average elevation of these hills is from 200-500 m. In Haryana, these hills mainly cover the area of Gurugram, Faridabad, Rewari, Bhiwani and Mahindragarh districts. These hills are found as lower, sporadic and dilapidated condition in Haryana. The highest elevated area of these hills is found in the South-West part of Narnaul town, which is 652 m high. It is called as Dhansi hills.
Floating Sandy Plains
These plains lie in the Mahendragarh, Rewari and Gurugram districts of Haryana. These plains are formed due to deposition of sand. In these plains, troughs are found in several places which are filled by water duriny rainy season.
This region is found in the Western region of the state in the district of Sirsa. It is the region with lowest elevation in the state i.e. below 200 m. It is result of water logging which has now turned into a wasteland.
Climate of Haryana
The climate of Haryana is influenced by sub-tropical wet climate of Himachal and Uttar Pradesh and semi-arid climate of Rajasthan. It has sub-tropical continental type of climate. Climate of Haryana is continental, characterised by very hot in summers and very cold in winters. South-Western Haryana has semi-arid type of climate while North and North-Eastern region has humid sub-tropical type of climate.

The Ambala district of the state receives the highest average rainfall, which is around 120 cm in a year, followed by Yamunanagar (1170-110 cm). The reason of highest rainfall here is that, it is surrounded by small hills. The district of Sirsa receives the lowest rainfall in Haryana, which is less than 35 cm. Chhachhrauli town in Yamunanagar is also known as Cherrapunji of Haryana, as it gets highest rainfall (110 cm) in the state.
