Exploring Earth's Systems and Changes

Front

What is a greenhouse gas?

Back

A greenhouse gas is a gas that traps heat in the atmosphere, contributing to the greenhouse effect and climate change. Examples include carbon dioxide, methane, and nitrous oxide.

Front

What is the primary greenhouse gas contributing to climate change?

Back

Carbon Dioxide (CO2) is the major greenhouse gas that contributes to climate change.

Front

What are wind patterns?

Back

Wind patterns are the movement of air masses in the atmosphere that result in changes in weather. They are influenced by the Earth's rotation and temperature differences.

Front

What is the theory of Plate Tectonics?

Back

Plate Tectonics is the scientific theory that describes the large-scale movement of Earth's lithospheric plates, which causes earthquakes, volcanic activity, and the formation of mountains.

Front

What is Continental Drift?

Back

Continental Drift is the hypothesis that continents have moved over geological time and were once joined together in a single landmass.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and gradually moves away from the ridge.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind, hydro), while non-renewable sources (e.g., petroleum, coal) are finite and will eventually deplete.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, where tectonic plates are located and where most geological activity occurs.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, composed mainly of iron and nickel, and is responsible for generating the Earth's magnetic field.
