A seismograph records four earthquakes of magnitude 3.7, 3.2, 6.5 and 4.3 and then seismicity decreases. Which earthquake(s) represent (a) foreshock(s)

Answers

Answer 1

Foreshocks are simply known as an earthquakes that often comes before a larger earthquakes in the same location. The earthquake 3.7 and 3.2 represent a foreshock.

Foreshocks as an earthquake cannot be said to be a foreshock until after a larger earthquake in the same area occurs.

Earthquakes that fall between the ranges of 3.0 to 3.9 on the scale are said to be small or minor earthquakes.

In this type of earthquakes, one can feel the earthquake, and objects inside shaking around, but it rarely damage.

Fertilizer adds missing chemicals back into the soil to make the soil more nutrient rich. These chemicals are needed for plants to survive and grow, and many of them are commonly found in the natural environment. How, then, can fertilizer also be a pollutant?

Answers

Excessive use of fertilizers leads to eutrophication. Fertilizers contain substances including nitrates and phosphorus that are flooded into lakes and oceans through rains and sewage. These substances boost the excessive growth of algae in the water bodies, thereby decreasing the level of oxygen for aquatic life.

the rain washes down the chemical fertilizer and discharge then into the river and many water bodies causing water pollution . when they are used the young seed that are sowed falls on them and that acts as a poison in the seeds . the use of chemical fertilizer can led to the spoiling of the quality of the soil

Natural gas emissions have no effect on global temperature increases.
D)
The burning of coal has had the greatest effect on global temperatures.

Answers

According to the information, we can state that global temperatures tend to increase as carbon emissions increase, as shown in option A.

We can arrive at this answer because:

According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.

These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.

On a geologic map, cratonic basins, where thick sequences of sedimentary rocks overly the Precambrian basement, show the _________ rocks toward the center of the basin.

Answers

On the geological maps in question, the cratonic basins that contain thick sequences of sedimentary rocks which overly the Precambrian basement, show the youngest rocks toward the center of the basin.

Geological maps are tools created and used by scientists to show the arrangement of the geological elements of a specific area. This can include:

Rock typesCracks and faultsMineralsGroundwaterAges

and much more, depending on the area and detail of the map created.

On a detailed geo-map, we can understand not only the area we are initially standing on but also where to find geological areas with similar sediment compositions and information on the age of the rocks. This is done due to the way the map stacks the units in terms of age, from the youngest at the top to the oldest at the bottom.

Cratonic basins are areas where geological elements are widely distributed and often filled with shallow water as well as sedimentary rocks. The rocks at the center of these basins show the youngest rocks at the center due to the previously mentioned aging sequence used by the maps.

water evaporates from the water bodies and forms clouds..then the clouds condense and finally precipitate in the form of rain,hail storms,snow etc..

hope it helps

Answer:

There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration

Explanation:

The water cycle depicts the continual flow of water on Earth and in the atmosphere. It's a complex system with many separate processes. Liquid water evaporates into water vapour, condenses into clouds, and precipitates as rain and snow on the ground.

Evaporation, condensation, and precipitation are the three fundamental processes that make up the water cycle. Evaporation is the transformation of a liquid's surface to a gas.

Liquid water (from the ocean, lakes, or rivers) evaporates and turns into water vapour in the water cycle. Water vapour is a significant greenhouse gas as well. Evaporation, condensation, and precipitation are commonly taught as a simple circular cycle.

Evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage are all processes that may be examined. When the physical condition of water changes from a liquid to a gaseous state, evaporation happens.

The water cycle is the course that all water takes as it passes through different phases across the Earth. Oceans, rivers, lakes, and even subterranean contain liquid water. The water cycle is the course taken by all water as it travels around our world.
