List and describe the sciences that collectively make up Earth science. Discuss the scales of space and time in Earth science.

Geology - this is the study of the solid Earth. Physical geology examines the materials that comprise the Earth

and historical geology aims to understand the origins and development of the planet.

Oceanography - examines the composition and dynamics of the world's oceans. It also involves the study of

coastal processes and seafloor topography as well as marine life.

Meteorology - this is the study of Earth's atmosphere. It includes weather and climate.

Astronomy - this examines Earth as a body in space, both as part of the solar system and as part of a larger

universe.

Environmental science - includes the study of natural resources, environmental hazards, and how people

influence their environments and Earth processes.

Name the two broad subdivisions of geology and distinguish between them.

Physical geology - this is the study of the materials and processes that define the planet Earth. It includes the

study of Earth's composition, events such as volcanism, and the dynamics of Earth processes such as plate tectonics.

Historical geology - this is the study of the origins and evolution of Earth. It pieces together a chronological

history of Earth based on clues in the rock record. These clues can include evidence of physical and biological

changes throughout Earth's 4.6 billion year history.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
