The scale is 1:50,000
Map scale : 1:50,000
Ground distance =22 x 50,000/100,000
The bearing of ungwan pa hausawa from kabso hill is 110°
Old scale =1:50,000
1/50,000 x2 = 2/50,000
New scale= =1:25,000
Length in map =48cm
Length of River Karami = 48 x 50,000/ 100,000 = 24km
The direction of river karami is south east
2960 KABSO HILL
Revolution of the earth is defined as the movement of the earth round the sun on its orbit
-It determines a year
-It Causes seasons
-Varying the length of day and night at different times of the year.
-It determines a year: The time taken by the earth to move round the sun
-It causes season: In tropical areas like west africa, including Nigeria,there are two seasons rainy season and dry season.
But in temperate Countries, the revolution of the earth causes four seasons.
-Varying the length of the day and night at different times of the year: The length of day and night varies depending on the position of the earth in relation to the sun
-It divides the globe into two halves or hemispheres
-They are equal in length
-The minor are of a great circle between two point is the shortest surface
– Is the largest possible circle that can be drawn around a sphere
-They are the straight lines of sphere
-They are the circumference of the circle
Climate change:this is the rise average surface Temperature on earth, mostly due to the turning of fossil fuels.It is also called global warming
Causes of climate change are;
-Burning of fossil fuels
-Increase in earth temperature
– industrial revolution
-Covertion of land forescend agriculture
-it affect agriculture product
-changes in the living of seasonal events
-it leads to rising in sea level
-it leads to human death and other consequences
Climate: This is defined as the average weather conditions of a place over a long period of time.
Latitude it refers to the location of a place on the earth’s surface in relation to the equator. Tropical latitude where the sun’s altitude is always high have hotter temperature than lower latitude this change in temperature affect climate
Altitude:this refers to the height of the place above the sun level.As one moves higher into the atmosphere, the temperature decreases by 6.5°c for every 1000m of ascent
Slope and aspect: Steep slope experience more rapid change in temperature than a gentle slope
-It aid soil formation by weathering
-it determines the type of crop to be cultivated in an area
-it Causes environmental hazard
-it determines the type of nature of vegetation in an area
-it helps in agricultural purposes
Remote sensing:this is the science and art of identify,without coming into direct contract with it.
-visible and infrared sensors.
– extracting mineral Deposits.
-Identifying crop conditions.
-Importing air traffic control.
– lift irrigation system..
-Extracting mineral deposit:earth holds more than 4000 natural elements,each with their unique chemical composition and spectral reflexive.remote sensing technology help to build potential map of these minerals.
-Fishing activities: fishermen save a lot of time and fuel by using satellites to monitor spa surface. In this process,remote. Spnsing technology is used to observe surface color and temperature to denue are full of fishes.
-identify crop conditions: satellite imagery and normalized difference vegetation index technologies art used in order. To maintain. Global supplies.
-Improving Air traffic control: this control the fow of air traffic.
-Lift irrigation system: a wide range of data is required. To design lift irrigation system for improving loater Supplies for agriculture and other industries
