Nature is filled with threes. Land, sea, and air. People propagate many plants by three chief methods. These methods are: (1) cuttage, (2) grafting, and (3) layering. Forests a catagirized into three major groups: (1) coniferous forests, (2) temperate deciduous forests, and (3) tropical rain forests.
The Earth orbits the Sun once a year in a nearly circular orbit.
The Earth’s axis of rotation (the straight line through the center of the Earth between the north and south poles) is not perpendicular to the plane of the Earth’s orbit. The Earth’s axis is tilted by about 23.4° from the the direction perpendiular to the orbital plane.
The orientation of the Earth’s axis in space remains nearly constant even as the Earth revolves around the Sun. It always points in the general direction of the star Polaris. Continue reading The Earth’s seasons→
Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx. Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

Madhya Pradesh has been receiving heavy to very heavy rains during the past few days. So much so that many cities have been witnessing rainfall in three digits. Satna is one such city which has been receiving extremely heavy rain for three consecutive days.
During the last 21 hours from 8:30 am on Thursday, Satna recorded a whopping 244 mm of rain. The rainy tale doesn’t end here. While the city recorded 131 mm of rain on Tuesday, a whopping 277 mm of rainfall was observed on Wednesday.
These rains can be attributed to the weather system which has been lingering close to Madhya Pradesh for quite some time now. The system had intensified into a depression increasing the rainfall intensity over the area. Now, the weather system has weakened into a low pressure area.
