Which statement describes gravity? check all that apply.1. there is no defined unit of measurement for gravity.2. gravity is the force that pulls objects toward earth’s center.3. objects that have a small mass will have no gravitational pull.4. gravitational pull between two objects increases as the mass of one increases.5. gravitational pull decreases when the distance between two objects increases.

1. There is not defined unit of measurement for gravity.

Newtons are the unit of measurement for gravity.

2. Gravity is the force that pulls objects toward Earth's center

Because the Earth is a sphere the gravitational pulls counteract with each other and it balances out in the middle, so if you were to fell the gravity of the center of the earth it would be weightless.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
