Summarize how oil is a global issue to be addressed for the future.
Morgarella [4.7K]

Answer:

Oil is a global issue because it is one of the most used resources for energy, but also one of the biggest polluters.

Explanation:

Oil is a natural resource that falls into the category of fossil fuels. It is a ofssil fuel that has helped the economies around the world to skyrocket and develop exponentially. This has been due to the properties of oil that releases enormous amounts of energy, thus it able to drive the industry forward.

This resource though also has become a huge problem. It is a big polluter, and it is obvious how much its usage has affected the atmosphere and environment in negative manner. Also, it is not unlimited, but eventually the reserves of it will end, so relying on it until that point will be devastating for the whole world. The whole world needs to work together, sooner rather than later, in order to gradually switch to energy sources that will be economically jutifiable but also environmental friendly, as if everything continous as until now the consequences will soon be irreparable and everyone will feel them.

lana66690 [7]

Explanation:

Air mass regions in the summer are usually around the middle latitudes of the Earth which means that they are closer to the Equator. This includes subtropical regions of the world including the subtropical Eastern Pacific and Western Atlantic Oceans.

Northern Mexico is also quite close to the middle latitudes so the most logical answer from the options is Central U.S. because it is the furthest from the equator and the middle latitudes of Earth.

Why February has 29 days during the leap year​
elena-s [515]

Explanation:

What is the day of the leap?

In the four-year cycle, an extra day is added to the calendar. Adjustments to ensure that our calendar is always in sync with the time the earth needs to be in front of the sun. Specifically, the Earth orbit lasts 365 days, 5 hours, 48 minutes and 46 seconds.

This extra 5+ hours is combined over time, so after four years, another day is added - the day of the leap - to our calendar with the sun.

When is the day of the leap?

Hell Day is February 29th. Why February? Because one of the goals of the calendar is based on the solar year, the Easter holiday in the spring. To do this, the calendar is set, so the vernal equinox is always on or near March 21st.
