Answer:
The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. The rock cycle by definition is a natural process by which sedimentary, igneous, and metamorphic rocks are created, changed from one type to another, and destroyed.
The Sedimentary Rocks is the type of the oldest rocks on Earth.
Sedimentary rocks, such as sandstone, are created by the compression of sediment or particles. ... The oldest whole rocks found so far date back about 4.28 billion years. They were found in 2001 by geologists excavating near Canada's Hudson Bay in northern Quebec, andthe research appeared in the Sept.

Answer:
If the same volume of air is inhaled and exhaled, the air we breathe out normally weighs more than the air we breathe in.
Since the output from the body normally exceeds the input, breathing leads to weight loss.
Explanation:
If equal volumes of gas is inhaled and exhaled, the exhaled gas is heavier.
The inhaled gas contains Oxygen and majorly Nitrogen.
The exhaled gas contains CO₂, H₂O and a very large fraction of the unused inhaled air that goes into the lungs.
So, basically, the body exchanges O₂ with CO₂ and H₂O (and some other unwanted gases in the body) in a composition that CO₂, the heavier gas of the ones mentioned here, is prominent.
So, because the mass leaving the body is more than the mass entering, breathing leads to a loss of weight. This is one of the reasons why we need food for sustenance. Breathing alone will wear one out.
Answer:
The speed of the plane relative to the ground is 300.79 km/h.
Explanation:
Given that,
Speed of wind = 75.0 km/hr
Speed of plane relative to the air = 310 km/hr
Suppose, determine the speed of the plane relative to the ground
We need to calculate the angle
Using formula of angle

Where, v'=speed of wind
v= speed of plane
Put the value into the formula



We need to calculate the resultant speed
Using formula of resultant speed

Put the value into the formula



Hence, The speed of the plane relative to the ground is 300.79 km/h.
