Explain how mars gravity may have resulted in less liquid water?
no because i dont know
How much gravity does the earth have please can you write it in terms a child can understand?
Its hard to explain it, but the equatorial surface gravity is 9.780327 m/s2 or 0.99732 gThe Earths gravity is around 380 ppm (pounds per mile).Sorry if this is too confusing!
What water cycle process works against gravity?
The process of transpiration works against gravity within the water cycle. During transpiration, water is absorbed by plant roots from the soil and then evaporates from tiny pores in the leaves into the atmosphere. This movement of water upward through plants, against the force of gravity, is facilitated by capillary action and the cohesion and adhesion of water molecules. Ultimately, this process contributes to the overall movement of water in the cycle.
When did Stephen hawking come up with Quantum gravity?
Stephen Hawking worked on quantum gravity throughout his career, but one of his notable contributions was made in the 1970s, when he investigated the quantum effects near black holes and proposed theories to explain the relationship between quantum mechanics and gravity.
How does gravity affect your blood?
Gravity affects the circulation of blood in your body by helping to return blood from your lower extremities back to your heart. When you stand upright, gravity pulls blood downwards, making it harder for your heart to pump blood against gravity. This can lead to higher blood pressure in your lower extremities and can contribute to conditions like varicose veins.
Why do veins in the head of a human have no valves?
The veins in your head dont need valves. Valves prevent backflow in the lower extremities because your bloodflow is going against gravity and your body is using muscular pumps to get the bloodflow back up to the heart. The blood flow in your upper extremities use gravity to get back to the heart via the superior vena cava.
Does peristalsis work against gravity?
Yes, peristalsis will work against gravity.
Lift something against gravity and you're measuring its?
Lift something against gravity and you're measuring its weight, which is the force acting on it due to gravity.
How could you explain to your friend that there is gravity in space and she thinks there isn't?
U tell her/him there is a gravity in space
What do you mean by center of gravity?
i dont know. you explain that to me
Who was the first to explain gravity in his law of gravitation?

How can you stand on earth explain?
Gravity keeps you on the earth.....
What is the force that acts against gravity?
The force that acts against gravity is called the normal force. It is exerted by a surface supporting an object, pushing upwards to prevent the object from falling due to gravity.
What would cause fluid retention in the legs and ankles of an elderly person?
Fluid frequently collects in the lower extremities of elderly people because their heart is not able to pump the fluid adequately and it backs up. The fluid settles to the lower extremities by gravity.
What is Gravity weathering?
I am not 100% sure, but I believe it is when gravity pick something up and it knocks against the rock, eroding it. It sometimes makes a small hole in the middle, and it sometimes causes there to be a part missing from the top of the rock.
Roots growing with gravity and stems growing against gravity are examples of?
Geotropism
