Which of the following is not a true statement:
Physical erosion can break rock apart.
Chemical erosion can break rocks apart.
Formation of stalactites is an example of chemical erosion.
Weathering and erosion can create soil.
Hello there, trinitibush!!
See, the formation of stalactites is not an example of erosion. Stalactites are an example of mineral deposits. Therefore, statement #3 must be false.

which are characteristics of a eukaryotic cell? A. single cellular, has nucleus.
B. Multicellular, has nucleus.
C. single cellular, has no nucleus.
D. Multicellular, has no nucleus.
Answer:
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.
Explanation:
The diagram on the left shows the layers of Earth's atmosphere and how temperature changes with altitude. The diagram on the right shows the layers of Venus' atmosphere and how temperature changes with altitude. Both diagrams indicate the altitude below which 90% of each atmosphere's mass is located.
According to the diagrams, which of the following statements is true?
A.
90% of the mass of Venus' atmosphere is within 10 km of the surface.
B.
The upper part of Venus' troposphere is about 200°C colder than the upper part of Earth's.
C.
Venus' troposphere is several times thicker than Earth's troposphere.
According to the diagrams. the following statements which is true is the upper part of the Venus' troposphere is about 200°C colder than the upper part of the Earth's atmosphere. Thus, the correct option is B.
What is the relation between troposphere and temperature?As the elevation increases, there is less air above us thus the pressure keeps on decreasing. As the pressure decreases, air molecules spread out further and expand in air, and the temperature of the atmosphere decreases.
Temperature of the atmosphere decreases with the increase in altitude because the troposphere is warmed from below, through the absorption and re-emission of incoming solar radiation by the Earth's surface, rather than it is being warmed from above through the incoming solar radiation.
According to the given diagram, the statement which is true is that the upper part of Venus' troposphere is about 200°C colder than the upper part of Earth's.
Therefore, the correct option is B.

How did the underwater volcano form?
Answer:
Underwater volcanoes form much like volcanoes on dry land by a process known as subduction.
Explanation:
This occurs as a result of tectonic plates which form the top layer of the Earth's mantle, just below the Earth's crust. They support the weight of the continents and the combined water of the seas.

Read the passage. Then write a paragraph that explains why the two ecosystems have such different kinds of plants. Use the terms biotic factor, abiotic factor, and limiting factor in your explanation.
Passage
A group of students is studying the types of plants that grow in a field next to the school. The field is mowed regularly, but it does not get any water other than rainfall. The field has several kinds of plants that are typically found in a grassland ecosystem. But it has none of the plants found in a nearby forest ecosystem.
Answer:
The reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, some biotic factors like animals or humans could be the reason. The humans may have planted seeds there, and probably some abiotic things like soil could also be the reason why. The plants that grow there receive a lot of rain, or the limiting factor is the rain, and the type of plants that grow there don't need much water to survive.

Explanation:
Answer:
Like a blowtorch, the heat transforms deep rocks into oozy magma. The magma rises upward until it erupts onto the seafloor. When the sizzling lava (which is what magma is called when it erupts) hits the cooler water, it hardens into an underwater volcano, the heat transforms deep rocks into oozy magma

How does the ocean interact with land and air?
Answer:
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.
Which of these types of environments is MOST LIKELY to experience the arrival of pioneer species?
A .an old growth forest
B. an undisturbed prairie
C. an established mountain lake
D. a newly formed volcanic island
Answer:
hey! the answer is D. ((A newly formed volcanic island)))
The type of environments is most likely to experience the arrival of pioneer species is a newly formed volcanic island. Thus, option D is correct.
What is environmental change?
Environmental change has a change or the disturbance of the climate which has been most often causes due to the human behavior, human activity or the natural ecological processes.
Environmental change has been consists many factors, such as the natural disaster, human interferences, or animal interactions. It has been also included physical change. Environmental change can also refers to the long-term shift in the temperature and weather patterns. These shifts may be the natural, such as through variations in the solar system.
In environmental change natural systems transform the sun's energy into living matter and cause changes by cycling material through geological, biological, oceanic and atmospheric processes. So environmental change has serious issue to our human society.
Therefore, The type of environments is most likely to experience the arrival of pioneer species is a newly formed volcanic island. Thus, option D is correct.
