What else can I help you with?
Will the pavement or grass heat up faster on a hot day and why?
Pavement will heat up faster than grass on a hot day because it has a lower albedo, meaning it absorbs more solar energy. Grass has a higher albedo and also benefits from transpiration, which helps to cool the surface.
Why is the air typically warmer on a sunny summer day in a parking lot than in the grassy field?
The concrete or asphalt of the parking lot reflects the heat much more than the green grass. The color of the grass helps and also the moisture in the ground/ grass will keep the temperature cooler.
Why is dry pavement creates more friction than ice pavement does?
Dry pavement creates more friction than ice pavement because when surfaces are dry, there is more contact between the tires and the road, leading to increased friction. On the other hand, ice has a low coefficient of friction, causing tires to slip more easily since there is less traction between the ice and the tires.
Why does soil absorb more solar radiation than grass?
Soil has a lower albedo (reflectivity) than grass, so it absorbs more solar radiation. This is because soil is typically darker in color and has a rougher surface compared to the smoother and lighter surface of grass. The absorbed solar radiation heats up the soil more compared to grass.
How types of ground surface affect air temperature?
Different types of ground surfaces such as grass, pavement, and water absorb and release heat at different rates. For example, pavement and buildings absorb heat quickly and release it slowly, leading to higher air temperatures in urban areas. On the other hand, grass and vegetation can cool the air through evapotranspiration and provide shade, resulting in lower air temperatures. Water bodies, like lakes or rivers, can also moderate temperatures by absorbing and releasing heat more slowly than land surfaces.
Will the pavement or grass heat up faster on a hot day?
Pavement will heat up faster than grass on a hot day because pavement absorbs and retains heat more effectively than grass. Grass tends to have a higher albedo, meaning it reflects more sunlight and absorbs less heat compared to pavement.
Why is it that pavement creates more friction than grass?
Pavement is smoother and harder than grass, providing a rougher surface for tires to grip onto, thus creating more friction. Grass has a softer and uneven surface, resulting in less traction and lower friction compared to pavement.
Will the pavement or grass heat up faster on a hot day and why?
Pavement will heat up faster than grass on a hot day because it has a lower albedo, meaning it absorbs more solar energy. Grass has a higher albedo and also benefits from transpiration, which helps to cool the surface.
Why is it easier to run across grass than it is along an icy pavement?
Well... An icy pavement doesn't have a lot of friction. Unless you have special shoes used for walking on ice that will give you better grip. Grass has a ton more friction than ice. But if you wanted to get even better grip, use cleats.

How erosion will be influenced by grass and shrubs?
Grass and shrubs reduce surface erosion by protecting soil from wind, rain and runoff. The roots of the plants also decrease erosion because a root ball has more stability than loose soil.
Why is more diffucult to walk on ice than on pavement?
Ice is seriously more slippy.
Why grass requires more rain than shrub?
Grass requires more rain than shrub as grass grows fast. It requires the nutrients more than a shrub.
Wet pavement is more slippery than dry pavement because of force needed to overcome what friction is less than the force needed to overcome sliding friction?
On wet pavement, the presence of water reduces the friction between the tires and the road surface, making it more slippery. This is because the force needed to overcome static friction (needed to start moving) is less than the force needed to overcome sliding friction (needed to maintain motion). As a result, it is easier for a vehicle to slide or skid on wet pavement compared to dry pavement.
Does transpiration effect dew on grass?
Absolutely. Air which is close to the ground cools overnight. While the air is cooling, the relative humidity is increasing until it reaches the dew point and water is released. Transpiration can also cause the dew point to be reached by increasing the relative humidity. This is why there is much more dew on the grass than on pavement.
Is concrete pavement can be used in highways?
Yes, Portland cement concrete pavement is often more economical in the long term than is asphalt concrete pavement. The asphalt concrete can be quite a bit faster to lay down and open to traffic, though.
