One of the following instruments is used in measuring the direction of wind
Cup anenometer
barometer
wind anenometer
wind vane
Correct answer is D
Cup anenometer is an instrument used for measuring the direction of the speed of wind
Barometer is used to measure air pressure and predicting changes in the weather
Wind vane is used to indicate the direction of the wind.
stratus
cirrus
altostratus
alto cummullus
Correct answer is B
Cirrus make up the high cloud and it is composed of ice-crystals, white and wispy. High clouds are cloud whose highest is between 6,000 m to 12,000m above the earth surface.
Stratus is one of the layers that make up the low cloud, altostratus is composed of water droplets partially covering the sky and it is also a part of middle cloud
Alto cumullus is also a distinct part of the middle cloud characterized by water droplets in layers with flattered bases in lines.
The high cloud is made up of three distinct parts which are cirrus, cirrocumulus, cirrostratus
One of the following properties of soil can be easily observed in the field
Fertility
Texture
Permeablity
Acidity
Correct answer is B
Texture has to do with feeling and touching. One can get to know if a soil sample is smooth or coarse by touching.
Testing a soil sample fertility can only be done at the laboratory with equipment, the same goes with testing of soil acidic properties.
Soil permeability involves introduction of liquid to know if the particular soil can retain water or not. It might be stressful as particular soil can retain water or not. It might be stressful as movement to get the liquid may be required unlike checking soil texture by just bending to the ground to prick and feel with the hand
The world has different time zone because
most countries do not agree on having the same time zone
it is a major way of differentiating countries from each other
the sum does not shine on the earth surface at the same time
the variation in weather and climate will not allow countries to have the same time zone
Correct answer is C
the sun does not shine on the earth surface at the same time. the earth spin on its axis, every 24 hours , the earth makes a complete rotation on its axis each rotation is called a day as the earth rotate different part of the earth receive sunlight and darkness

Ox-bow lake
Meander
V-shaped valley
Artificial embankment
Correct answer is C
V-shaped valley is formed as a result of vertical erosion of a river which makes it deeper with step sides because the water as active in following
Ox-blow lakes are crescent-shaped lakes formed by running water flowing through a meander neck. It is formed at the lower course of a river
Meanders are found at the middle course of a river network
Artificial embankment is a long artificial mound of stone or earth, built to hold back water
