Explanation:
it is a geologic time period
The answer is C. it would become ice
Answer: Option (D)
Explanation: In the water cycle, water is transported from the oceans, seas and lakes to the atmosphere, which then again falls back due to precipitation.
Plants also absorbs water by their roots and releases back into the atmosphere by evapo-transpiration process. Some of the water gets percolated into the ground and gets mixes up with the groundwater.
Thus all the provided options fulfills the condition for water cycle except the last one, i.e dissolution of CO₂ in the ground water or the land surface is not considered to be a part of water cycle.
Hence the correct answer is option (D).
Answer:
The moons gravitational force at different points on the earth
Explanation:
The perstubation force of the sun on the moon at two places in its orbit . The blue arrows represent the direction and magnitude of the gravitational force on the Earth. Applying this to both the Earth's and the Moon's position does not disturb the positions relative to each other. When it is subtracted from the force on the Moon (black arrows), what is left is the perturbing force (red arrows) on the Moon relative to the Earth. Because the perturbing force is different in direction and magnitude on opposite sides of the orbit, it produces a change in the shape of the orbit.
In astronomy , perturbation is the complex motion of a massive body subject to forces other than the
gravitational attraction of a single other
massive body .
