Why you need remote sensing image classification?
Remote sensing image classification is important for various applications such as land cover mapping, urban planning, environmental monitoring, and disaster management. It allows for the extraction of valuable information from satellite or aerial images, enabling decision-making processes in various fields. By categorizing different features in the images, classification helps in better understanding and analysis of the Earth's surface.
What is the process in which rocks first bend and then break?
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
Are volcanos formed by erosion?
The cone volcanoes are created by the upwelling of liquid hot rock from the earth's interior. This is called Plutonic rock, along with Granites which however are cooled before they reach the surface. The hollow left at the top of a volcano is formed when the pool of magma withdraws and the volcano becomes quiet.
Some volcanoes do not form cones. Lake Taupo in New Zealand, and Yellowstone National Park in the US are notable examples, where there was a violent explosive eruption which however did not produce a local cone.
The volcanic eruption, whose caldera is now filled in by Lake Taupo occurred about 26000 years ago and ejected over 1 000 cubic kilometres of material! It has had 28 eruptions in the last 27 000 years, and in one it ejected about 30 cubic kilometres in a few minutes. The last eruption was about AD 186.
Naturally, once erupted, erosion takes its toll on the exposed and fairly unstable material.
There is a third type of volcanic material, the Flood Basalts, which are of continental scale! These ejections are of a very liquid material, covering giant areas, but without conspicuous surface relief.
Would a field represented by a contour map be likely to change with time?
Typically, the underlying physical field represented by a contour map, such as elevation or temperature, does not change appreciably over short periods of time. However, dynamic fields like weather patterns or vegetation cover can change rapidly and may require frequent updates to reflect the current state.
How does extrusive differ from intrusive?
Extrusive rocks form from lava cooling on the Earth's surface, leading to rapid cooling and fine-grained texture. Intrusive rocks form from magma cooling beneath the surface, resulting in slower cooling and coarse-grained texture. This difference in cooling rates gives extrusive rocks their characteristic fine-grained appearance and intrusive rocks their coarse-grained appearance.
Well, bio means life, and disposition may be a characteristic quality (NOT a disadvantage or advantage). So the environment of a fresh water fish and a fresh water crocodile might be similar, for example, but each likely has a different biodisposition.
What is the breaking down of sediment?
The breaking down of sediment is called weathering. This process involves the physical and chemical breakdown of rocks and mineral particles into smaller fragments. Weathering can occur through processes such as erosion, abrasion, and chemical reactions.
What is the name of the method used to find the volume of a regular object?
The method used to find the volume of a regular object is typically called the "displacement method" or "calculating volume by measuring dimensions". This involves measuring the length, width, and height of the object and then multiplying these dimensions together to find the volume.
How do i use the earth's magnetic field to tell me where to go?
You can use a compass to detect the Earth's magnetic field and determine cardinal directions like North, South, East, and West. By aligning the compass needle with the magnetic field, you can navigate and orient yourself accordingly.
No! It's not gonna end today, from the beginning of the week you would have seen signs big ones at that, there has been alot of rain this week where I live but that's it. It doesn't even look like dooms day, enjoy your weekend
Who is Mohs hardness scale named after?
The Mohs hardness scale is named after Friedrich Mohs, a German geologist and mineralogist who created the scale in 1812. It is used to determine the relative hardness of minerals by their ability to scratch each other.
What speed is the pacific plate moving?
The Pacific Plate is moving at an average rate of about 3 to 10 centimeters per year, in a west-northwest direction. This movement is driven by the global process of plate tectonics, where the Earth's lithosphere is divided into several large plates that move relative to each other.
Where does the global current conveyor belt begin?
The global current conveyor belt begins in the North Atlantic Ocean, where warm water from the Gulf Stream moves northward to the Arctic. This warm water eventually cools and sinks in the Labrador Sea, starting a deep current that travels southward along the ocean floor.
Is making a cup of tea an example of diffusion or osmosis?
Diffusion is the correct answer as a tea bag is a fully permeable surface. (Unlike Cellophane and other semi permeable membranes). Osmosis is the process where water passes through a semipermeable membrane.
Those are called jet streams. They form at the boundaries between hot and cold air masses and can reach speeds of over 100 miles per hour. Jet streams play a crucial role in shaping global weather patterns.
How many cm does a bean plant grow in 3 weeks?
The growth of a bean plant can vary, but on average it can grow around 10-15 cm in 3 weeks under optimal conditions. Factors such as species of bean plant, soil quality, sunlight, and water availability can all affect the rate of growth.
What is the production of two useful forms of energy from the same fuel source called?
Cogeneration, or combined heat and power (CHP), is the production of electricity and useful thermal energy (such as heat or steam) from the same fuel source in a single process. This process increases the overall efficiency of energy production compared to separate generation methods.
What causes rocks to be smooth and rounded?
Rocks become smooth and rounded through a process called abrasion. This occurs when the rocks are continuously rubbed against each other or against other surfaces, wearing down their rough edges and surfaces over time. Factors such as water flow, wind, ice, and sand can contribute to this process.

How might you determine the speed of your car if the speedometer broke?
You can estimate your speed by using landmarks and a timer. Choose a fixed point and measure the time it takes to reach it. Calculate your speed by dividing the distance to the fixed point by the time taken to reach it. Alternatively, use a GPS app on your phone to track your speed.
What time of the day does the sky turn red?
The sky can turn red during sunrise or sunset due to the scattering of sunlight in the atmosphere. This phenomenon occurs when the sun is low on the horizon, and the red wavelengths of light are scattered more than other colors, creating vibrant red and orange hues in the sky.
What is the relationship between the temperature and the number of daylight hours?
In general there is a delay between the highest daylight hours and highest temperatures and between lowest daylight hours and lowest temperatures. The reason is energy absorbed. When the sun is pounding down during the summer the highest temperatures come approx 1 month after the longest day of the year because the enrgy absobed on the earth in the oceans and on land has a commulative effect. The same thing happens in winter.
What happenes to these sediments as they move around?
Sediments move around due to the combination of the force of gravity acting on the sediment and or the movement of the fluid in which the sediment is entrained. Movement may either be made by air, water or ice. Sediment movement in fluids occurs in water bodies as a result of water currents and tides.

What percent of fresh water is in the form of liquid?
Approximately 69% of fresh water on Earth is in the form of liquid, primarily found in rivers, lakes, and groundwater. The remaining fresh water is stored in frozen form in glaciers and ice caps.
