SCIENCE FORM 1 - CHAPTER 9 (EARTH)

The Earth system consists of four main components. One of them are

• Exosphere

• Hydrosphere

• Stratosphere

• Mesosphere

The ___________ also known as the ionosphere because it contains ions that can reflect radio waves.

The statements refers to

• Igneous rock

• Sedimentary rock

• Metamorphic rock

Choose two factors that are required in metamorphic rock formation (Pick two correct answers)

• Compression

• Pressure

• Freezing

• Heat

What does "X" in the diagram represent?

• Magma

• Lava

• Asthenosphere

• Crust

Earth has many processes that affect the changes of Earth. An example of process that occurs on Earth's surface is

• Mantle convection process

• Crust movement

• Magma activity

• Soil erosion

Which of these is a process of rock fragmentation and decomposition due to exposure to rainwater and temperature?

• Mass depletion

• Sedimentation

• Weathering

• Erosion

Which statement represents the diagram?

• Weathered materials are moved by running water such as river and lake

• Rock decomposes due to exposure to temperature, rainwater, and microorganisms

• Eroded material on Earth's surface by water, wind and waves

• Involve soil movement from the top of a slope to below causing phenomenon like landslide

Process that is caused by forces from within the Earth does not change the Earth's surface

• True

• False

High temperature in the mantle and the ___________ of Earth produces convection currents in the asthenosphere (below lithosphere) layer.

• Lithosphere

• Mesosphere

• Inner core

• Core
