For many years, scientists thought that the ocean floor was flat. During World War II, U.S. Navy ships patrolled the oceans. A captain of one of the ships, Harry Hess, was also a geologist. He used a new device called an echo sounder to map the ocean floor. The echo sounder data showed that the ocean floor had mountains and volcanoes in addition to flat areas.
When scientists took samples of the rocks that made up the ocean floor, they discovered something surprising. The rocks closer to the mid-ocean ridge were younger in age than the rocks far away from the mid-ocean ridge. They concluded that this difference in age was another way to support the theory of plate tectonics.

Which best describes how the scientists could explain their observations?

A They thought that sediment washing in from the shore formed the

ocean floor, and continued to build out from the shore.

B They thought that strong ocean waves pushed the younger rock material toward the middle of the ocean

C They thought that wave erosion at the shore removed the younger rock layers that were on top of the older rock layers.

D They thought the young rock formed at the mid-ocean ridge and pushed the older rock toward the shore

Explanation:

An air mass is a body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, or millions of square kilometers. A front is the boundary at which two air masses of different temperature and moisture content meet.

Answer:

Answer:

Heat (the phase change caused by heat is called melting)

If there is a significant difference in air temperature between two adjacent regions, then it is expected that areas of high pressure will form over the colder region, while areas of low pressure will develop over the warmer region.

Based on the given information, we can hypothesize that the distribution of high and low-pressure areas on the surface Pressure Map will be influenced by the temperature gradient across different regions. If there is a substantial difference in air temperature between adjacent areas, then we can expect the formation of areas of high and low pressure. The colder region will experience higher air pressure, as the colder air tends to be denser and sinks, creating an area of high pressure. Conversely, the warmer region will exhibit lower air pressure, as the warmer air expands and rises, leading to the formation of an area of low pressure.

The temperature gradient plays a crucial role in atmospheric circulation patterns, as it drives the movement of air masses and the development of pressure systems. The pressure differences between high and low-pressure areas influence wind flow, leading to the movement of air from high-pressure to low-pressure regions. Therefore, understanding the relationship between temperature gradients and pressure systems is vital for predicting weather patterns and identifying areas of potential atmospheric disturbances.

To reduce the negative impact caused by human activities on the river, it is necessary to think of solutions that promote sustainability and introduce new ways of disposing of waste produced by individuals and organizations.

It is essential that each individual is aware of his or her active role as a citizen, establishing simple attitudes that can generate positive impacts on the environment, such as recycling personal waste and using green transport.

Therefore, in addition to the correct disposal of urban waste, the use of alternative and renewable energies are also measures that must be implemented to promote the sustainability of rivers.

This polygon is called Nonagon.

Explanation:

The first picture is of hygrometer.

Hygrometer, instrument used in meteorological science to measure the humidity, or amount of water vapour in the air.

Hygrometer works on the phenomenon called evaporative cooling. When water evaporates from any surface, it becomes cool because water molecules take heat energy from the surface during the evaporation. Due to this cooling effect wet bulb always shows low temperature than the dry bulb.

The second picture is of thermometer.

Thermometer for measuring air and sea surface temperature.

A thermometer has a glass tube sealed at both ends and is partly filled with a liquid like mercury or alcohol. As the temperature around the thermometer's bulb heats up, the liquid rises in the glass tube. The glass tube is mounted on a backboard that is marked in units called degrees.

The third picture is of barometer.

Barometer for measuring atmospheric pressure.

The barometer works by balancing the mercury in the glass tube against the outside air pressure, just like a set of scales. As air pressure increases—that is, as the air becomes heavier—it pushes more of the mercury up into the tube. ... So the level of mercury in the tube provides a precise measure of air pressure.

Importance of weather forecasting:-

Systematic weather records play an effective role in various professions, particularly for agriculture and businesses that are dependent on it. Agricultural processes like planting and harvesting can be planned better and carried out more efficiently if long-term weather patterns can be estimated.

On the other hand, Airlines is another region where weather plays a vital role. They need to recognise the local weather conditions in order to schedule flights. Weather forecasting helps them make perfect daily decisions, and may even help keep us out of danger.

Answer:

-5x² +6x

Explanation:

The given expression is :

-3x(x-4)-2x(x+3)

It can be done as follows :

-3x(x-4)-2x(x+3) = (-3x)(x)-(-3x)(4) - 2x(x)-2x(3)

= -3x² +12x -2x² -6x

= -3x²-2x² +12x-6x

= -5x² +6x

Hence, the equivalent expression is equal to -5x² +6x.

Answer: a. True

Explanation:

Both regional and flash floods are a result of the release of large quantities of precipitation and/or snow-melt.

Winter and spring rains combined with melting snow overfill river basins and flood the banks, triggering regional floods. Regional floods can also happen when there's lots of rain, which saturates the soil and allows runoff to flood into streams and rivers. A flash flood, also triggered by heavy rains, is a local flood, meaning that it occurs in a small geographical region.
