how does the rock cycle support the explanation that "matter is never created or destroyed?"
Answer:
The chemical elements that make up minerals and rocks are not destroyed. This fact illustrates the principle of conservation of matter. The changes that take place in the rock cycle never destroy or create matter. The elements are just redistributed in other forms.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells.
Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?
A
tree trunks that become smaller branches and twigs
B
a tight flower bud that has opened into a full bloom
C
whole apples that are sliced into separate wedges
D
a bridge that crosses two rivers

How do different climate zones respond to severe weather?
What challenges does each climate zone face?
How can that climate zone be best prepared for severe weather?
Which climate zone is the safest to live in? Why?
Answer: 1. It just depends on what climate, for example Higher temperatures mean warmer seas, higher sea levels and more moisture evaporating into the atmosphere.
2. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.
3. Prepare by making sure that everything will stay in the same spot and check the forecast.
4. In North America because there is not a lot of very severe storms
