Answer:
True
Explanation:
The bigger an object is, the more force you must apply to move the object. Think about it like moving a mouse compared to moving an elephant. You can't move the elephant by yourself, because you don't have enough strength or force to move it. But, you can easily pick up a mouse, because it requires less force, or strength. Hope this helped :)
The existence of atmosphere increases the average planetary temperature by more than 15°C, due to the greenhouse effect of some atmospheric compounds. The most important of them are water vapour (H2O), ozone (O3), carbon dioxide (CO2), and methane (CH4).

3.cuz if they are not used properly they can cause injuries to organs
When warm currents move over cool land surface, they dissipate heat due to
the temperature gradient . They hence warm up the land they blow over. If a
cold current blows over warm land, the land loses heat to the current. This is
how currents distribute heat across the earth.
When the current blow from water to land, the current will be warm or cold
depending on the water temperatures. Therefore, they will warm up or cool the adjacent
land mass.
