The Grand Canyon is about 5-6 million years old, or was formed about 5-6 million years ago
Answer:
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
Explanation:
This problem can be solved as a simple rule of three, with the mathematical conversion from feet to m.
Each ft has 0.3048m. So how many m are there in 7.6ft?
1 ft - 0.3048m
7.6ft - x m
So
A hydraulic conductivity of 7.6 ft/day converts to 2.3 m/day.
Slowly, deep underground
The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.
Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
According to the Pew Research Center 74% consider climate change to be a serious problem and 77% say that it is harming people now, 20 points higher than the global median. The same study showed that 63% of people in Latin America are very concerned that climate change will harm them personally.
