The volcanoes can be seen on the topographic map as tall peeks. How many volcanic peaks higher than 7000 feet can be seen on this map.

Explanation:

Each line represents an increase in height of 1000ft.

And the volcano peaks are the circles with no other concentric lines inside (meaning that does not grow anymore, so it is the peak).

We can see that the peak of the top volcano has 13 lines, so it is around 13,000 ft high.

The bottom volcano has also 13 lines, so it is also around 13,000 ft high, then in the image we can see two volcanos higher than 7000ft.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
