The long-term relationship between solar activity features (sunspot number, solar flare index 10.7), geomagnetic indices (Dst and Ap) and CRI (Moscow neutron monitor) are considered. Simultaneous investigations have been made to evaluate the identical relationship between solar and geomagnetic disturbances with CRI variation. We have found that solar activity has eleven-year periodicity, while geomagnetic indices follow different periodicity. It has been found that Dst is in opposite phase with Ap index, while SSN and SFI are in the same phase. We observed that CRI provides inverse and high correlation with SSN (r=-0.95), SFI (-0.97), Dst (0.82), and average correlation along with Ap (-0.50). Large anomalies are observed in Ap index rather than SSN, SFI and Dst index. The frequency of solar flare and coronal maas ejection is directly linked with SSN, SFI, Dst and Ap index. Thus, the present study will help to analyze the X-rays classification and also their impact on Earth's climate with solar activity, cosmic ray intensity and geomagnetic indices.
