Answer:
The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection.
Explanation:
The water cycle
Water on Earth is constantly moving. It is recycled over and over again. This recycling process is called the water cycle.
1. Water evaporates into the air
The sun heats up water on land, in rivers, lakes and seas and turns it into water vapour. The water vapour rises into the air.
2. Water vapour condenses into clouds
Water vapour in the air cools down and changes back into tiny drops of liquid water, forming clouds.
3. Water falls as precipitation
The clouds get heavy and water falls back to the ground in the form of rain or snow.
4. Water returns to the sea
Rain water runs over the land and collects in lakes or rivers, which take it back to the sea. The cycle starts all over again.
Answer:
A house has high heating bills because the heat ends up in the attic, and The movement of air in a hot-air balloon makes it rise into the sky.
Explanation:
<span>The <u>PHYSICAL</u> environment is the earth, air, water, landscape, weather, and even sound. The <u>SOCIAL</u> environment is other people and what they contribute.
This is how the general community works and functions. Ideally it should be a mutual understanding between the two environments, but humans are more capable of destroying the physical environment benefiting from its abundant resources.

Potential Energy
The potential energy gained is 43750 J
Explanation:
Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.
For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.
Potential Energy is defined as
Potential energy = Mass * height
Given Mass M = 1250 N
Given height h = 35 m
So the potential energy = 1250 * 35 = 43750 J
Thus the potential energy is 43750 J
Answer:
the inner core is solid because S-waves stop at the inner core. The strong magnetic field is caused by convection in the liquid outer core.
