Answers

Answer:

plains form as ice and water erodes, or wears away, the dirt and rock on higher land.

when the time is 2am at GMT,it is already 5am at place X. calculate the longitude of place X.​

Answers

Answer: 45°E

Explanation:

The lines of longitude can be used to determine the time of an area.

Every 15° line of longitude away from the Prime Meridian is an extra hour away from the time at the Prime Meridian.

The Prime Meridian is GMT and is the 0° longitude.

Areas that are ahead of GMT are to the east of the Prime Meridian and those behind GMT are west.

If the time is 5am in place X and it is 2am in GMT, the time difference is:

= 5 - 2

= 3 hours

Place X is ahead of GMT so they are to the east of the Prime Meridian.

3 hours in degrees is:

= 3 * 15

= 45°

Place X is 45° east of the Prime Meridian so is labelled as 45°E.

When warm, moist air rises, it generally loses temperature as atmospheric pressure decreases at higher altitudes. Air's ability to hold water vapor is decreased as pressure is reduced and cools adiabatically and eventually reaches its saturation level. As a result, rising air becomes unable to hold water vapors (air is saturated), leading to condensation and then followed by precipitation.

What happens when warm moist air rises?

Warm, humid air will cool and expand if it rises. When a surface cools, water condenses as the relative humidity rises. Then, as precipitation, it might return to the ground.

When warm, humid air rises into the cold air, thunderstorms are created. As the warm air cools, condensation occurs, which is the formation of tiny water droplets from water vapor. The atmosphere's cooled air sinks warms and then rises once more.
