GEOGRAFI STPM SEMESTER 1: TENAGA

The first learning objective is to study the concept of energy. The second

explain the type and source of energy. The third, differentiate exogenic energy and endogenic energy. Energy Concept Energy is a means or force to do work. Energy cannot be created, but changes form from one form to another form.

Two main types of energy are endogenic and exogenic. Endogenic energy consists of gravity, radiogenic energy, hydrogel energy, and geothermal energy.

while the exogenic energy consists of chemical energy, kinetic energy, sound energy and energy of effort. Energy Source Energy source for the endogenic energy and exogenic energy is the exogenic energy source from the outside of the earth, namely from the sun.

while the Indogenic force originates from the Earth's stomach, namely from the energy of the wind, gravity and radiogenic energy. Next, we will learn about the Sun's energy as the main source of energy to the Earth's system. The learning objectives for this topic consist of three objectives

First, explain the four ways of moving solar energy. Second, explain the six factors of the difference in solar reception. And finally, explain the importance of the sun to the physical and human. First objective, how to move solar energy.

Sun energy is transferred to the earth through four main ways. The first is by flow. Through the flow of energy, the energy flows from the hot body to the cold body. The second way is through the sun. Before the sun reaches the earth, the sun will undergo a process of radiation, radiation and radiation.

The third way is through the process. The process occurs when liquid flows in contact with the liquid or cold liquid. The last way is the radiation. Radiation occurs through a short electromagnetic wave that forms ultra-lighting. Sunlight

received on the Earth's surface differ by region. The factors of the difference in the reception of solar energy are caused by six main factors, namely the first is caused by the circulation of the Earth around the sun. During the hot season solstice, the sun is bright in the line of Saturn.

causing the northern hemisphere to experience a longer day. The effect is that the area receives the maximum amount of sunlight. The second factor is caused by the Earth's rotation. The area facing the sun will receive sunlight, while the protected area does not receive sunlight.

The third factor is caused by the earthquake of the Earth. The earthquake of the Earth is 23.1 degrees, causing during the hot season solstice, the northern hemisphere to experience three days. The fourth factor is caused by the cloud cover.

The area located in the equator has thick clouds, while the desert area has very thin clouds, causing the sun to be received is very high. The fifth difference in receiving materials is the growth envelope factor.

Areas with thick forests receive less sunlight. And the last factor is the aspect and height factor. Aspects refer to the part of the earth's surface that is exposed to the sun. Whereas high areas receive more sunlight. The importance of solar energy to the physical.

The importance of the sun to the physical is to refer to the four main components of the earth, namely the first one, the lithosphere or geomorphology component. The second component is the importance of the atmosphere,

The third component is the importance of the sun to the hydrosphere or hydrology component. And the last is the importance of the sun to the biosphere or ecology component.

To answer the question of the importance of the sun to the physical, the student can choose any process that exists from the four systems of the earth. Example of the question, explain the importance of the sun to the physical, the environment around the physical or the physical environment, the answer is as follows.

The first fact is the importance of the sun for the air flow process. An example of a pattern is the physical air flow process such as the salt plucking process occurs because the strong sunlight in the desert area causes the groundwater to be polluted.

The second answer is important to the fertilization process. The definition is: The fertilization process of crops is active when they receive a lot of sun. Example The third answer is the importance of the sun to the eruption of the Berapi Mountain. Example

Sunlight causes the temperature on the surface of the Asthenosphere to rise. The increase in temperature causes the friction current on the Asthenosphere layer to become more rigid, causing lava to be forced out into the holes of the mountains. The third and fourth answer is the importance of the process of construction.

The process of sedimentation on the surface of water occurs due to high amounts of sunlight. The fifth answer is the importance of food chain. Plants need solar energy to carry out photosynthesis processes to produce food.

The production of chemical energy through the photosynthesis process supplies food to the primary consumer. And the last point is the importance of the body movement process. The sun's rays cause the glacier to melt and fall below the mountain.

Next, we will learn the importance of solar energy to humans. The importance of the sun to humans or to the environment around humans or to human life is seen from two main aspects. The first aspect is the domestic aspect. The second aspect is economic activity.

So for questions like this, for example, explain the importance of the sun to humans or the nature around humans or human life.

Students can give answers from these two groups of answers, namely the first, the facts can be taken from the domestic aspect and the second from the economic activity aspect. Example of questions Explain the importance of the sun to humans or human life. Example of answers

The importance of the sun for agricultural activities. For example, agricultural activities such as planting paddy require a lot of sunlight because the crop growth will be good if you receive enough sunlight. That's all our lesson today.
