An exploding volcano, for instance, devastated all adjacent living things in Mount Saint Helens, Washington.
What consequences resulted from Mount St. Helens' 1980 eruption?Numerous homes, buildings, and other structures were destroyed, resulting in the deaths of 57 individuals. Following the eruption, the Mount St. Helens summit was gone, forests were destroyed, and rivers took on new paths. More than 150 new lakes and ponds were created, while the sediment from already-existing lakes filled the banks of the former, drowning them.
How did the volcanic eruption of Mount St. Helen in 1980 affect biodiversity?The 1980 explosion at Mount St. Helens resulted in the loss of around 90 square miles of forest habitat, but boosted habitat for lakes and ponds by a factor of five.

What does geological structure mean?
The strong tectonic forces that occur within the earth are typically what cause geologic structures. These forces result in deep faults, rock folding and breaking, and mountain formation.
The study of the three-dimensional distribution of rock units in relation to their deformational histories is known as structural geology. The main objective of structural geology is to understand the stress field that produced the observed strain and geometries by using measurements of the current rock geometries to learn about the history of deformation (strain) in the rocks.
A common objective is to comprehend the structural evolution of a specific region with respect to regionally widespread patterns of rock deformation (for example, mountain building, rifting) caused by plate tectonics. This understanding of the dynamics of the stress field can be linked to significant events in the geologic past.

two students are talking about what causes the tides. student a says that the tide comes in and goes out based on differences in the height of the sea level. student b says that the changing tides are caused by earth rotating into and out of the tidal bulges. which explanation is more technically correct? why?
Technically, student A is more accurate. The difference in sea level height, according to student A, is what causes the tide, whereas the earth's rotation in and out of the tidal bulges, according to student B, is what causes the shifting tides.
The daily rise and fall of the tide is brought on by the gravitational pull of the sun and moon, according to the definition of the general cause of tides. The varying heights of the water during the day correspond to the rising and falling of the tides. The varying distance between the earth and the moon is what causes the daily variations in tide heights.
In order to study tides and the different phenomena that affect tides, such as hurricanes and winter storms, scientists monitor the height of the water level. They result from the earth's gravitational pull from the moon and, to a lesser extent, the sun. A shore experiences a high tide when the wave's highest point, or the crest, reaches it. A coast suffers a low tide when the trough, or lowest point, approaches it.

what type of weathering occurs when joints within rocks are aligned so that layers of rock break off and new layers are exposed?
When joints within rocks are aligned, a type of weathering known as mechanical weathering takes place whereby layers of rock break off and new layers are revealed.
Due to the fact that nature is constantly active, even if this activity occurs more slowly than human senses can perceive, mechanical weathering is a physical process that occurs continuously in the environment. As an illustration, we can feel temperature changes from day to night, yet we cannot see a rock swell and shrink as a result of these temperature changes. The rock does, however, experience this imperceptible movement, which weakens it and finally leads to its fracture and breakdown. This is just one instance of mechanical weathering. Let's examine each of the several mechanical weathering processes in more detail.

Granite and basalt rocks are exposed at the earth's surface in a hot, wet climate. Will mechanical weathering or chemical weathering predominate? which rock will weather more rapidly? be sure to explain your rationale.
Chemical weathering would impact basalt more because its minerals are more unstable to surface weathering processes than granite.
What type of chemical weathering affects granite?Chemical weathering from water will affect granite. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. The clay weakens the rock, making it more likely to break.Mechanical weathering, also known as physical weathering and disaggregation, causes rocks to crumble. Water, whether liquid or solid, is a common mechanical weathering agent. Liquid water, for example, can seep into cracks and crevices in rock.Basalt and granite share a lot of similarities.

Some scientists claim that they can determine when the earth first formed as a planet. which technique do scientists use today to determine when the earth first formed?
The technique which scientists use today to determine when the earth first formed is called as Analysis of uranium and lead in meteorites.
The concepts of radiometric dating and their use in calculating the age of the Earth are explained by geologist Ralph Harvey and historian Mott Greene. As uranium decays in rocks, it produces subatomic particles and converts to lead at a steady pace. Measuring the uranium-to-lead ratios in the planet's oldest rocks gave scientists an estimate of 4.6 billion years.
The discovery of radioactivity at the turn of the century was a watershed moment. Scientists found that pebbles may literally be used as watches. Many chemical elements in rock exist in a variety of slightly different isotopes.
Certain isotopes are unstable and undergo radioactive decay, slowly and steadily converting into a new isotope molecule by molecule. The rate of decay for a given isotope is constant, and the time it takes for one-half of a particular isotope to decay is known as its radioactive half-life.
Every 100 million years, for example, around 1.5 percent of Uranium 238 will decay to lead. The age of a rock sample may be established by examining the ratio of lead to uranium in it. Scientists may "look" back in time using this technique, known as radiometric dating.

The largest river in the world is the Nile River! Spanning across 4.132 miles, it begins in the rivers that flow into Lake Victoria (located in modern-day Uganda, Tanzania, and Kenya) and empties into the Mediterranean Sea more than 6,600 kilometers to the north, making it one of the longest river in the world.
The Nile River flows from south to north through eastern Africa. From its headwaters in Ethiopia and the central African highlands to the downstream regional superpower Egypt, the Nile flows through 10 nations;, Burundi, Tanzania, Rwanda, the Democratic Republic of the Congo, Kenya, Uganda, Sudan, Ethiopia, and South Sudan. But by a quirk of British colonial history, only Egypt and its neighbor Sudan have any rights to its water.
The Nile River flows north from its source. This river flows over 4,100 miles before it reaches the Mediterranean Sea, the location of the Nile Delta. It also has three main tributaries which are the White Nile, the Blue Nile, and the Atbara.
The Nile Rivers composes of 4 main dams;
Aswan High Dam, Aswan High Dam
Sudan, the Sennar Dam on the Blue Nile River.
Grand Ethiopian Renaissance Dam in Ethiopia.
"The water quality of mid-stream Nile water is still, at a clean level on an average, due to the dilution effect and the degradation of the discharged pollutants." (Abdel-Satar, 2005). But that was in 2005, a few environmental challenges have been introduced since then and some are ones that need to be dealt with. Egypt is also believed to face a nationwide fresh water shortage by 2025. Already around seven percent of Egyptians lack access to clean drinking water and over eight million go without proper sanitation. The waters are mainly being polluted by municipal and industrial waste, with many recorded incidents of leakage of wastewater, the dumping of dead animal carcasses, and the release of chemical and hazardous industrial waste into the Nile River.

Do whales sink when dead?
When a whale dies it float over the ocean surface due to the gas build up and eventually they sink. It is called as whale fall.
When whale dies the body will float to the bottom . Once the body comes to rest biologists refer to this as a whale fall. other fish and sea animals initially eat the meat off the carcass. Bacteria that overtake a whale skeleton feed off the bones. The bacteria then produce hydrogen sulfide. Those thousands of chemoautotrophic sea creatures convert the hydrogen sulfide into usable energy to thrive and reproduce. Once a whale dies it may float at or near the ocean's surface for a few days due to gas buildup but eventually the carcass sinks, carried by ocean currents and often landing in the deep sea. These whale falls are rare but are most often seen along the migratory routes of living whales.
