The period of time between 12:00pm and sunset.

3. Aftershock

Aftershocks are Earthquakes that follow the largest shock of an Earthquake sequence. They are smaller than the "main-shock" and can continue to occur over a period of weeks, months, or years.
In general, the larger the main-shock, the larger and more numerous the aftershocks, and the longer they will continue.

4. Air Pressure

Air pressure is the difference in pressure from one place to another. Air pressure always moves outward from a high or inward toward low-pressure. The bigger the difference between these two measurements, the stronger the wind will blow. Pressure is caused by the weight in the air and is measured by barometers. In general, weather will improve when pressure increases and worsen when pressure decreases.

5. Alto

Middle-layer clouds (alto) typically form anywhere between 10,000 feet (3 km or 2 miles) and 23,000 feet over the Earth.
Such clouds are developed from both ice crystals and water droplets, and range between 32°F/0°C and below freezing.
This type of cloud is thicker than cirrus clouds and consists mainly of two types: altocumulus and altostratus.
