Latitude is a geographical coordinate that is used to locate the north and the south position of a location on the earth's surface.
Explanation
- Latitude can be defined as an angle that varies from 0 degree at the equator to 90 degree at the poles.
- Latitude affects the temperature of the earth in the following ways :-
- As a person moves away from the equator the temperature of the regions away from the equator falls this is because the region receives less sunlight.
- The shape of the earth is not round it is spheroid that is the reason all the regions on the surface of the earth do not receive the same amount of sunlight.
From the above given options the 2 correct choices are
- Latitude determines the duration of the day:The areas at the equator (i.e at 0 degree latitude) the length of the day is said to be 12 hours,now as the latitude increases to 80 degree (i.e at the polar circles) the length of the day increases to 24 hours or decreases to zero.
- Latitude creates Polar and temperate zones:There are three types of latitude zones-Arctic,temperate and tropic zone.Latitude is considered as an important parameter in the classification of zones as it correlates to the amount of sunlight a region receives.
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
Answer:
Humus (hummus) is a dark organic matter in the soil which is produced by the decay of leaves or twigs (leaf litter). The litter is decayed in the soil by the action of microbial communities and chemcial reactions (together called as biogeochemical reactions). This process is also known as decomposition. The higher humus content in the soil makes it more fertile because there are more nutrients releasing due to increased turnover of the decomposing bacteria. Further, humus formation is increased if more water (moisture content) and oxygen is available.
