Science Flashcard

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What causes valleys to form?

Back

Valleys can form due to erosion by rivers, glaciers, or other geological processes.

Front

What is physical weathering?

Back

Physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition, often through freezing and thawing.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or other chemicals.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, shaping the landscape through erosion.

Front

What is the role of water in shaping the Earth's surface?

Back

Water plays a major role in shaping the Earth's surface through processes like erosion, transporting sediments, and forming landforms.

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis, involving controlled variables and data collection.

Front

What are controlled variables?

Back

Controlled variables are factors in an experiment that are kept constant to ensure that the results are due to the independent variable.

Front

What is the difference between an observation and an experiment?

Back

An observation is simply noting and recording data, while an experiment involves manipulating variables to test a hypothesis.

Front

What is the significance of recording data in scientific studies?

Back

Recording data is crucial for analyzing results, drawing conclusions, and validating or refuting hypotheses.
