Why is the seasonal temperature range greater at 45N than at 45S?
The seasonal temperature range is greater at 45N than at 45S because the Northern Hemisphere has more landmass compared to the Southern Hemisphere, which tends to heat up and cool down more rapidly than water. Land has a lower heat capacity and can experience more extreme temperature variations throughout the year.
Where would gullies be more likely to form a field with plowed soil and no plants or a field covered with thick grass Explain.?
Gullies are more likely to form in a field with plowed soil and no plants because the bare soil is more prone to erosion by water runoff. Thick grass in a field helps to reduce water runoff, prevent soil erosion, and stabilize the ground, making it less likely for gullies to form.
The ability of the environment to support the population?
The ability of the environment to support a population refers to its carrying capacity, which is the maximum population size that can be sustained based on available resources like food, water, and shelter. When a population exceeds the environment's carrying capacity, it can lead to resource depletion, competition, and potential collapse. Maintaining a balance between population size and available resources is crucial for the long-term sustainability of ecosystems.
Which factor will most likely increase the carrying capacity of a mouse population in a forest?
: High rains increase the water supply.
What aspects of rice cultivation are apparent?
Key aspects of rice cultivation include selecting the right variety, preparing the field for planting, managing water levels, applying fertilizers and pesticides as needed, and monitoring plant health throughout the growing season. Post-harvest activities such as drying, milling, and storage are also crucial for successful rice cultivation.
Why does the field capacity remain the same throughout the year?
Field capacity remains the same throughout the year because it represents the maximum amount of water that soil can hold against gravity after excess water has drained away. It is a physical property of the soil that is not influenced by changes in weather or seasons.
What is field capacity of soil?
Field capacity is the maximum amount of water that soil can hold against the force of gravity after excess water has drained away. It represents the water content in soil that is available to plants for uptake. At field capacity, the soil is typically at its optimal moisture level for plant growth.
What is field capacity?
Field capacity is the maximum amount of water soil can hold after excess water drains away. It is the point at which gravity overcomes the forces of water absorption and retention in the soil. Field capacity helps determine when plants need watering and ensures proper soil moisture for crop growth.
How to determine PLANT available water?
You take the difference in the water content between field capacity and wilting point
Is soil and water a solution suspension or a colloid?
Soil and water form a suspension when mixed together because the soil particles do not dissolve in water but remain dispersed throughout the liquid.
What is surface runoff?
water flow which occurs during or after rain, when soil is infiltrated to full capacity and excess water.
Does a stream's discharge remain the same throughout its course?
No, a stream's discharge does not remain the same throughout its course. Discharge can vary due to factors such as precipitation, evaporation, and tributary inflow. Typically, discharge increases downstream as more water is added from tributaries and runoff. However, it may decrease in areas where water is lost through infiltration or evaporation.
What threatens the sustainability of water?
Sustainability is the capacity to endure. In ecology, the word describes how biological systems remain diverse and productive over time.Sustainablility of water is affected by pollution and availability. Many water resources are diminishing through overuse.
Is boiling water to make steam a permanent change?
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
What is made when salt is dissolved in water?
When salt is dissolved in water, it forms a solution where the salt molecules are evenly dispersed throughout the water molecules. This is a physical change as the salt and water molecules remain the same, only their arrangement has changed.
How does the air's capacity to hold water change as elevation increase?
As elevation increases, temperature decreases approximately at the rate of 12.5 degrees c every 1km upwards. As air temperature decreases, its capacity to hold water is less. Therfore as elevation increases, its water capacity will decrease.
How does mica powder behave when mixed with water?
When mica powder is mixed with water, it tends to form a suspension where the particles of mica are dispersed throughout the water. The mica particles do not dissolve in water but instead remain suspended, giving the mixture a shimmery or glittery appearance.
