Answer:
Radiation and advection
Explanation:
- Conduction: It happens when particles of matter are in direct contact, the adjacent atoms of higher energy vibrate against each other transferring energy from high to low temperature. Fluids and gases are less conductive than solids because their atoms have a greater distance. An example is the heat transferred between the electric burner of a stove and the bottom of a pan.
- Convection: Is a heat transference between a surface and a liquid or gas in motion, as the fluid/gas travels faster the transferred heat increases. An example of this transfer takes place in a forced-air furnace and weather systems.
- Advection: is similar to convection but the transfer of heat is lateral or horizontal. In the atmosphere this kind of transfer is common.
- Radiation: is the transfer through empty space, it occurs without an intervening medium when microwaves, infrared radiation, visible light or another electromagnetic radiation is emitted or absorbed. An example is the sun warming the Earth.
Advection and radiation are the primary forms of heat transfer. Convection only happens in the troposphere because horizontal heat transfer (advection) is significantly bigger. The same happens with conduction that only transfers heat in the lower layers of the atmosphere, Sun's radiation, on the other hand, gets absorbed in all the atmosphere.

Answer:
Five professional are Cartographer, Town planner, Teachers, Gis experts, Demographers,
Explanation:
- As cartography is the art and science of making maps the Cartographers use geographic data on maps from various maps, diagrams and define locational boundaries. Use the geographic principles of the globe to form models of the earth's surface.
- Town planners or urban geographers use the art of geography to interpret and plan the cities formation and development, they also use the basic geographic techniques like zoning and land-use patterns of a city, the internal structure, etc.
- Teachers, they use their knowledge of geography to teach and develop approaches so as the student can understand the world better, they use innovative ideas and out of text information to spread this body of knowledge far and wide.
- Demographers, generally study the population parameters based on the statistics and data collected from the surveys both primary and secondary. Population studies also come under this field, and analysis the population age and sex ratio, etc.
- Gis experts or professional working with the software need to have a thorough knowledge of geography as it helps them to formalise and plan various types of maps the as they are governed by the government bodies and private groups in the country.
Answer:
Option: A. True
Explanation:
The Maya civilization covers regions that spread from northern Mexico southwards into Central America. The Maya stretched from modern-day southern Mexico through Guatemala, Honduras, and Belize. The culture is renowned for its massive pyramids, irrigation systems and agriculture, and symbols. Most of the ruins are still discover in the jungles of Mexico and Guatemala, which remain unknown since the colonial period in Mexico under the Spanish Empire. The civilization fizzled out between A.D. 800 and 1000 before the arrival of Spanish in Central America that led structures remain untouched in the jungle for centuries.
