Answer 1

Answer:

• 1.Geography is often defined in terms of two branches: human geography and physical geography. Human geography is concerned with the study of people and their communities, cultures, economies, and interactions with the environment by studying their relations with and across space and place.

• 2.The recent techniques that helped the geographers is GIS(Geographic Information Systems) and GPS (Global Positioning System).

• 3.Physical geography was conventionally subdivided into geomorphology, climatology, hydrology, and biogeography.

1. Biogeography is the study of the distribution of life forms, past and present, and the causes of such distributions. It includes the application of biochemical techniques for genetic analysis and application the large-scale analysis, incorporating remote sensing, of biogeographical patterns; studying and modelling ecosystem dynamics and metapopulation dynamics; poblems of speciation and genotypic variation; and the analysis and daing of the palaeo-biogeographical record. Biogeographers may also be concerned with environment-related food and health issues.
2. Climatology - the study of the origins and impacts of climates.
3. Geomorphology is the study of the nature and history of landforms and the processes which create them. Initially, the subject was committed to unravelling the history of landform development, but to this evolutionary approach has been added a drive to understand the way in which geomorphological processes operate. In many cases, geomorphologists have tried to model geomorphological processes, and, more recently, some have been concerned with the effect of human agency on such processes.
4. Hydrology - the study of the Earth’s water, particularly of water on and under the ground before it reaches the ocean or before it evaporates into the air. This science has many important applications such as flood control, irrigation, domestic and industrial water supply, and the generation of hydroelectric power.

• 6.The knowledge about interior of the earth is obtained through direct sources and indirect sources. Direct sources include rock materials from mining areas and molten magma from volcanic eruptions. Besides, scientists are working on “Deep Ocean drilling Project” and “Integrated Ocean Drilling Project”

• 7.Magma is composed of molten rock and is stored in the Earth's crust. Lava is magma that reaches the surface of our planet through a volcano vent.

• 8.The three types are composite volcanoes, shield volcanoes, or cinder cone volcanoes. The cinder cones are small volcanoes with steep sides.

• 10.An Earthquake is a sudden shaking of the Earth's crust due to sudden release of energy. The three types of earthquake waves are:- p-wave, s-wave,surface wave. p-wave:- they are primary because they are fastest. s-wave:-they are secondary because they are slower. surface wave:-It is the seismic wave trap near the earth.

• 11.Seismologists are Earth scientists, specialized in geophysics, who study the genesis and the propagation of seismic waves in geological materials.

Answer 2

Answer:

1. Geography is often defined in terms of two branches: human geography and physical geography.

2. The recent techniques that helped the geographers is GIS(Geographic Information Systems) and GPS (Global Positioning System).

3. Physical geography was conventionally subdivided into geomorphology, climatology, hydrology, and biogeography, but is now more holistic in systems analysis of recent environmental and Quaternary change.

4. The REGIONAL approach studies the many characteristics of each region (or realm) of the world. This is the approach of your textbook and the main approach used in this course. SYSTEMATIC geography, on the other hand, studies one issue and looks at its spatial variations in all parts of the globe.

5. human geography offers a new conception of the interrelationships between earth and human beings . Human geography studies the inter-relationship between the physical environment and socio-cultural environment created by human beings through mutual interaction with each other.

6. The knowledge about interior of the earth is obtained through direct sources and indirect sources. Direct sources include rock materials from mining areas and molten magma from volcanic eruptions. Besides, scientists are working on “Deep Ocean drilling Project” and “Integrated Ocean Drilling Project”.

7. Scientists use the term magma for molten rock that is underground and

Lava for molten rock that breaks through the Earth's surface.

8. Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas. Learn about these volcanic landforms and how they are created.

9.The structure of the Earth is divided into layers. These layers are both physically and chemically different. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid center called the inner core.

10. An Earthquake is a sudden shaking of the Earth's crust due to sudden release of energy. The three types of earthquake waves are:- p-wave, s-wave,surface wave. p-wave:- they are primary because they are fastest. s-wave:-they are secondary because they are slower. surface wave:-It is the seismic wave trap near the earth.

11. Seismologists are Earth scientists, specialized in geophysics, who study the genesis and the propagation of seismic waves in geological materials. ... At the Geological Survey of Canada, the Seismology and Electromagnetism Section carries out such research.

The area of the fault where the sudden rupture takes place is called the focus or hypocenter of the earthquake. The point on the Earth's surface directly above the focus is called the epicenter of the earthquake.

Magnitude measures the energy released at the source of the earthquake. Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location.
