Earth science

Question 1

What is Earth Science?

Answer 1

Earth Science is the name for the group of sciences that collectively seek to understand the Earth and its neighbors in space.

Question 2

Earth is a large and complicated place. How do scientists study it?

Answer 2

No one scientist studies all parts of the Earth, instead different scientists study different parts of the planet.

Question 3

What are some of the branches of Earth Science?

Answer 3

Astronomy
Geology
Meteorology
Oceanography
Biology

Question 4

What is Geology?

Answer 4

It is the study of the origin, history, and structure of the Earth. It includes the study of the processes that shape Earth. It also deals with the study of the history of all life that’s ever lived on Earth.

Question 5

What are the two main types of Geology and give examples of each.

Answer 5

The two types of Geology are physical and historical Geology. Examples of physical geology are Volcanology and Seismology.
Historical geologists study history of the Earth: change through time. Paleontologists study the history of life on Earth.

Question 6

What is Geochemistry?

Answer 6

Geochemistry combines the studies of geology and chemistry.

Question 7

What do Geochemists use Geochemistry?

Answer 7

They study the chemicals that make up Earth materials such as rocks, minerals, and soil. They use this information to learn how the Earth materials formed. They also study the effects of human-made chemicals on the environment.

Question 8

What is Geography?

Answer 8

Its an all- encompassing discipline that seeks an understanding of the Earth and its human and natural complexities. It studies the surface features of the Earth such as continents, rivers, and mountains, lands, the inhabitants.

Question 9

What is physical geography?

Answer 9

The branch of geography which deals with the study of processes and patterns in the natural environment like geomorphology.

Question 10

What is Oceanography?

Answer 10

The study of the seafloors, coastal processes.

Question 11

What are somethings oceanographers may focus on?

Answer 11

Biological oceanographers study the living things in the ocean.
Chemical oceanographers study the amounts of different chemical in ocean water.
The physical aspects of the ocean such as depth and extent of ocean waters, their movement and the topography.

Question 12

What is Meteorology?

Answer 12

A branch that deals with Earth’s atmosphere, especially weather and climate. It is a branch of the atmospheric sciences which includes atmospheric chemistry and atmospheric physics.

Question 13

What do meteorologists do?

Answer 13

Meteorologists try to forecast or predict the weather, sometimes to help save people’s lives by predicting severe weather, these predictions can warn people to leave an area before severe weather strikes.

Question 14

What is Astronomy?

Answer 14

The study of the universe, the study of the universe is important in probing the origins of our own environment.

Question 15

What are Astronomers?

Answer 15

Astronomers are scientists who study star, asteroids, planets, and other objects in space.

Question 16

Why is astronomy a branch of Earth science if astronomers study objects far from the Earth?

Answer 16

The reason is that many astronomers use information about other planets and stars to learn more about the Earth. The information they gather can help them to predict how changes in our sun may affect the Earth.

Question 17

Why is Earth Sciences important?

Answer 17

To provide life-saving warnings of e.g., floods, hurricanes, and volcanic eruptions.
To understand how human activities influence the environment.
To better prepared to understand the processes that occur within and between each of the Earth systems.

Question 18

What is the universe about?

Answer 18

It is all time and space. Defined as everything that is in space, time, that is existing, that will exist. It contains some form of energy. This includes all planets, it is believed to be 13.7 billion years.

Question 19

What is The Big Bang Theory?

Answer 19

Is the most widely accepted theory about the origins of the universe. The universe began about 13,7 billion years ago, everything squeezed in a small hot and chaotic volume. An enormous explosion took place and the universe expanded rapidly releasing all the matter and energy in the universe, and even space.

Question 20

How did the Earth form?

Answer 20

The Nebular hypothesis, which has served to present an type of evolution of the solar system and a basis for interpretation of the origin of the Earth. It suggests that the bodies of our solar system evolved from an enormous rotating cloud called the solar nebular. It was made up mostly of hydrogen and helium, with a small percentage of heavier elements. Shortly after the Earth formed, melting occurred in the Earth’s interior. Gravity caused denser elements to sink to Earth’s center. Less dense elements floated towards the surface. As a result, Earth is made up of layers of materials that have different properties.

Question 21

What is Creationism?

Answer 21

Creationism is the religious belief that the Universe and life originated “from specific acts of Divine creation, creationism holds that the physical universe was created by God, do so by faith. Base their beliefs on reading religious texts including the Biblical Genesis creation (Genesis 1: 1-2) and from the Quaran.
