Answer;
The above statement is true
Human impact on one system leads to changes in more of Earth’s systems.
Explanation;
Events can occur naturally, such as an earthquake or a hurricane, or they can be caused by humans, such as an oil spill or air pollution. An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres.
Human impact on one system leads to changes in more of Earth’s systems because things like carbon and methane emissions affect the environment, which affects all plant and animal life.
Answer:
0.1667Hz
Explanation:
by explanation frequency is given by 1/time
after carrying out the calculation of time we can easily get frequency.
time=speed/distance
=18/3
=6s
but frequency=1/time
hence=1/6
=0.1667hertz
jason paints 1/4 of the area of his living room walls on Monday = Wi =1/4
On Tuesday, he paints twice as much as he painted on Monday=Wf=2Wi
=Wf =2 X 1/4
= Wf = 1/2
total painted area =W(TOTAL)= Wi+Wf =1/4 + 1/2 =1/2
reaining painted area = W =1 - 1/4 - 1/2 = 1/4
