Answer:
gravitational pull of the sun
Explanation:
The primary factor that keeps Earth orbiting around the sun is the sun's gravitational pull. This force not only keeps Earth in its path but also governs the orbital motions of other celestial bodies in our solar system. The influence of gravity goes beyond keeping the Earth in orbit, affecting seasons, time, and the behavior of other celestial bodies.
The primary factor that keeps Earth in orbit around the sun is the gravitational pull of the sun. According to Newton's universal law of gravitation, the gravitational force is related to mass and distance, which is what keeps the planets in orbit. This force explains why the Earth and other planets follow a specific path around the Sun.
Orbital motions are governed by this gravitational force, and as a result, the Earth, acting similar to a large gyroscope, has its angular momentum along its axis aligning with Polaris, the North Star. The movements of the Earth due to gravity cause the seasons, determine our sense of time and date, and contribute to the concept of months and lunar phases. Meanwhile, the gravity from other planets can produce slight variations in our orbit, a process that requires large computers to calculate accurately.
In the broader context of the Solar System, gravitational force plays a crucial role. Besides keeping Earth in orbit, it influences the orbits of artificial satellites and other celestial bodies like asteroids and comets. If the gravitational interaction of more than two objects is to be calculated, it becomes complicated and requires extensive computing power. However, when an object, like the Sun in our solar system, dominates gravitationally, it's possible to calculate the effects of a second object in terms of small perturbations.

Answer:
Option (1)
Explanation:
Out of all the water body (total composition) present on earth, about 97% is the ocean saline water and the remaining 3% comprises the freshwater that includes the water of the rivers, lakes, streams and ponds.
Again, from this total amount of freshwater (3%), the glaciers and ice caps cover nearly 68% of it, groundwater covers about 30% and some other surface (fresh) water comprises the remaining 2%.
So, in simple words, it can be concluded that about 2% (68/100*3) of the freshwater is occupied by the glaciers.
Thus, from the given options, the most approximate value is 2.15% which is option (1).
Answer:
The Tundra ecosystem in the far northern Russia runs parallel to the 'arctic shoreline'.
Explanation:
A) Choctaw
B)Cherokee
C) Illini
D) Inuit
A. torora reed
B. lichens
C. indigo
D. pampas grass
The lichens is the plant species which can be found in Atacama Desert
The Atacama Desert is a desert plateau that sits between the Andes and Chilean Coast Range in the South America.
The Atacama Desert is regarded as one of the driest desert and receives very small amount of rainfall annually.
The desert does not support lives because of its harsh nature as been the driest hot desert in the world.
However, the lichens which is a plant species can be seen in such condition because its is not really a complete plant, rather, it is because its has complex life form of a fungus and an alga.
